Diese Seite erklärt die image Syntax beim Bearbeiten des Wikis. Normalerweise musst du oder ein anderer Nutzer ein Bild hochladen bevor es auf der Seite benutzt werden kann.

Auf einem MediaWiki Server gespeicherte Bilder werden normalerweise dargestellt mit dem Präfix File: für den Datei-Namensraum als Ziel für einen MediaWiki Link. (Die alte Schreibweise Image: wird noch immer als Synonym unterstützt). Das alternative Namensraum-Präfix Media: kann ebenfalls genutzt werden, um den originalen Dateiinhalt zu bezeichnen (um ihn separat auf jeder MediaWiki Seite anzuzeigen oder herunterzuladen).

Unterstützte Bildformate

Die folgenden Formate werden standardmäßig unterstützt.

  • .jpg oder .jpeg : Bitmap Bilder im Standard JPEG Format komprimiert (dieses verlustbehaftete Format ist am besten geeignet für Fotos).
  • .png : Bitmap Bilder im Portable Network Graphics Format (Spezifiziert vom W3 Consortium).
  • .gif : Bitmap Bilder im alten Graphics Interchange Format.

Andere von Wikimedia verwendete Formate, die üblicherweise anderswo aktiviert sind (diese bedürfen möglicherweise zusätzliche Konfiguration, da sie mitunter nicht standardmäßig aktiviert sind):

Andere Medientypen können unterstützt werden, aber nicht deren Darstellung in einer Zeile.

Anzeigen eines einzelnen Bildes

Syntax

Die vollständige Syntax für das Anzeigen eines Bildes ist:

[[File:filename.extension|options|caption]]

Option kann keine oder mehrere der Folgenden sein, getrennt durch den vertikalen Strich (|):

  • Format Option: eine von border und/oder frameless, frame, thumb (oder thumbnail);
    Bestimmt wie das angezeigt Bild auf der Seite formatiert und eingebettet wird.
  • Grösse anpassen (resizing) Option: eine von
    • {width}px — ändert die Bildbreite auf das angegebene Maximum, ohne die Höhe festzusetzen.
    • x{height}px — ändert die Bildhöhe auf das angegebene Maximum, ohne die Breite festzusetzen.
    • {width}x{height}px — ändert die Bildgrösse um innerhalb der Höhe und Breite zu liegen.
    • upright — ändert die Größe innerhalb sinnvoller Ausdehnungen, gemäß Benutzervorgaben (geeignet für Bilder mit größerer Höhe als Breite).
    Hinweis: das Seitenverhältnis wird immer bewahrt und das Bild kann nur verkleinert (nicht vergrößert) werden, außer wenn es sich um einen skalierbaren Typ handelt (Bitmap Bilder können nicht hochskaliert werden).
    Die maximale Standartgröße hängt ab vom Format und den internen Bildmaßen (gemäß des Medientyps).
  • Horizontale Ausrichtungs Option: eines von left, right, center, none;
    Bestimmt die Horizontale Ausrichtung (und inline/block oder floating Stile) des Bildes innerhalb von Text (ohne Standartwert).
  • Vertikale Ausrichtungs Option: eines von baseline, sub, super, top, text-top, middle, bottom, text-bottom;
    Bestimmt die vertikale Ausrichtung eines non-floating inline Bildes mit dem Text vor oder nach dem Bild innerhalb des selben Blocks (die vertikale Standartausrichtung ist middle)
  • Link option: Eine von

Example.jpg** link={target} — Erlaubt das Ändern des erzeugten Linkziels (zu einem zufälligen Seitentitel oder URL), aktivierbar auf der angezeigten Bildfläche ; z.B. [[File:Example.jpg|20px|link=http://www.wikipedia.org]] wird dargestellt als Example.jpg (externer Link), oder [[File:Example.jpg|20px|link=MediaWiki]] als Example.jpg (interner Link).

    • link= (mit einem Leerwert) — (MediaWiki 1.14+) Zeigt ein Bild ohne aktivierbaren Link; z.B. [[File:Example.jpg|20px|link=]] wird dargestellt als Example.jpg.
      • ! für MW Version 1.24 und kleiner: Wenn |link=|, also nicht angegeben ist, dann wird beim überfahren mit dem Mauszeiger abhängig vom benutzten Browser nicht zwingend ein Text angezeigt (siehe phabricator:T23454).
  • Andere spezifische Optionen:
    • alt={alternativer Text} — (MediaWiki 1.14+) spezifiziert alternativen Text (bezogen auf das HTML Attribut alt="..." des generierten <img /> Elements) eines Bilds, der angezeigt wird, wenn entweder das gewünschte Bild nicht heruntergeladen und angezeigt werden kann oder das anzeigende System diesen Text verwenden muss (z. B. wenn ein Braille-Leser eingesetzt wird oder der Nutzer im Browser entsprechendes einstellt).
    • page={Nummer} — zeigt die angegebene Seitennummer (zur Zeit nur verwendbar, wenn eine *.djvu- oder eine *.pdf-Datei angezeigt wird).
    • class={HTML Klasse} — (MediaWiki 1.20+) Definiert die Klassen (spezifiziert das HTML-Attribut class="..." des generierten <img /> Elements).
    • lang={language code} — (MediaWiki 1.22+) For SVG files containing <switch> statements varying on a systemLanguage attribute, selects what language to render the file in. The default is always English, even on non-English wikis.

Wenn ein Parameter mit keiner der anderen Möglichkeiten übereinstimmt, wird davon ausgegangen, dass er der Beschriftungstext ist. Beschriftungstext wird unterhalb des Bildes in thumb und frame Formaten angezeigt oder als Tooltip-Text in jedem anderen Format. Der in den Formaten thumb und Frame angezeigte Beschriftungstext kann Wiki-Links und andere Formatierungen enthalten. MediaWiki Erweiterungen können zusätzliche Optionen hizufügen.

Wenn 'alt' nicht angegeben wird und eine Beschriftung vorliegt, wird der Alternativtext automatisch aus der Beschriftung ohne Formatierung erstellt.

Format

Die folgende Tabelle zeigt die Auswirkung aller verfügbaren Formate.

When the height of an image in thumbnail is bigger than its width (i.e. in portrait orientation rather than landscape) and you find it too large, you may try the option upright=N, where N is the image's aspect ratio (its width divided by its height, defaulting to 0.75). The alternative is to specify the desired maximum height (in pixels) explicitly.

Note that by writing thumb={filename}, you can use a different image for the thumbnail.

Größe und Rahmen

Among different formats, the effect of the size parameter may be different, as shown below.

  • For how it appears when its size is not specified, see Format section above.
  • When the format is not specified, or only bordered, the size can be both reduced and enlarged to any specified size.
  • In the examples below, the original size of the image is 400 × 267 pixels.
  • An image with frame always ignores the size specification, the original image will be reduced if it exceeds the maximum size defined in user preferences.
  • The size of an image with thumb can be reduced, but can not be enlarged beyond the original size of the image.

Vertikale Ausrichtung

The vertical alignment options take effect only if the image is rendered as an inline element and is not floating. They alter the way the inlined image will be vertically aligned with the text present in the same block before and/or after this image on the same rendered row.

Note that the rendered line of text where inline images are inserted (and the lines of text rendered after the current one) may be moved down (this will increase the line-height conditionally by additional line spacing, just as it may occur with spans of text with variable font sizes, or with superscripts and subscripts) to allow the image height to be fully displayed with this alignment constraint.

To show the alignment result more clearly, the text spans are overlined and underlined, the font-size is increased to 200%, and the paragraph block is outlined with a thin border; additionally images of different sizes are aligned:

text top: Example.jpg Example.jpg Example.jpg text

text text-top: Example.jpg Example.jpg Example.jpg text

text super: Example.jpg Example.jpg Example.jpg text

text baseline: Example.jpg Example.jpg Example.jpg text

text sub: Example.jpg Example.jpg Example.jpg text

text default: Example.jpg Example.jpg Example.jpg text

text middle: Example.jpg Example.jpg Example.jpg text

text text-bottom: Example.jpg Example.jpg Example.jpg text

text bottom: Example.jpg Example.jpg Example.jpg text

Hinweise:

  1. The "middle" vertical alignment position of the image (which is also the default) usually refers to the middle between the x-height and the baseline of the text (on which the vertical middle of the image will be aligned, and on which usually the text may be overstroke), but not to the middle of the line-height of the font-height that refers to the space between the "text-top" and "text-bottom" positions ; the font-height excludes:
    • the additional line separation spacing normally divided equally into two line-margins (here 0.5em, according to line-height set to 200%) above and below the font-height).
    • the additional line spacing which may be added by superscripts and subscripts.
  2. However, if the image height causes its top or bottom position to go above or below the normal full line-height of text, the middle position will be adjusted after the increasing the top and/or bottom line-margins so that the image can fit and align properly, and all images (including those with smaller heights) will be vertically centered on the adjusted middle position (for computing the effective line-height, the text of each rendered row with the larger font-height will be considered).
  3. The "text-top" and "text-bottom" alignment positions also excludes the extra line spacing added by superscripts and subscripts, but not the additional line-spacing defined by the line-height.
  4. The "top" and "bottom" alignment positions take into account all these extra line spacings (including superscripts and subscripts, if they are present in a rendered line span). When the image alignment constrains the image to grow above or below the normal line-spacing, and the image is not absolutely positioned, the image will cause the "top" and "bottom" positions to be adjusted (just like superscripts and subscripts), so the effective line-height between rendered lines of text will be higher.
  5. The "underline", "overline" and "overstrike" text-decoration positions should be somewhere within these two limits and may depend on the type and height of fonts used (the superscript and subscript styles may be taken into account in some browsers, but usually these styles are ignored and the position of these decorations may not be adjusted); so these decorations normally don't affect the vertical position of images, relatively to the text.

Stopping the text flow

On occasion it is desirable to stop text (or other inline non-floating images) from flowing around a floating image. Depending on the web browser's screen resolution and such, text flow on the right side of an image may cause a section header (for instance, == My Header ==) to appear to the right of the image, instead of below it, as a user may expect. The text flow can be stopped by placing <br clear=all> (or if you prefer, <div style="clear: both"></div>) before the text that should start below the floating image. (This may also be done without an empty line by wrapping the section with the floating images with <div style="overflow: hidden">…</div>, which clears all floats inside the div element.)

All images rendered as blocks (including non-floating centered images, left- or right-floating images, as well as framed or thumbnailed floating images) are implicitly breaking the surrounding lines of text (terminating the current block of text before the image, and creating a new paragraph for the text after them). They will then stack vertically along their left or right alignment margin (or along the center line between these margins for centered images).

Altering the default link target

The following table shows how to alter the link target (whose default is the image description page) or how to remove it. Changing the link does not alter the format described in the previous sections.

Warnung::

The licencing requirements on your wiki may not allow you to remove all links to the description page that displays the required authors attributions, the copyrights statements, the applicable licencing terms, or a more complete description of the rendered image (including its history of modifications).
If you change or remove the target link of an image, you will then have to provide somewhere else on your page an explicit link to this description page, or to display the copyright and author statement and a link to the applicable licence, if they are different from the elements applicable to the embedding page itself.
Your wiki policy may restrict the use of the alternate link parameter, or may even enforce a prohibition of alternate link parameters for embedded media files (in which case, the link parameter will be ignored), or may only accept them after validation by authorized users or administrators.


Rendering a gallery of images

Gallery syntax

It's easy to make a gallery of thumbnails with the <gallery> tag. Die Syntax ist:

<gallery>
File:file_name.ext|caption|alt=alt language
File:file_name.ext|caption|alt=alt language
{...}
</gallery>

Note that the image code is not enclosed in brackets when enclosed in gallery tags.

Captions are optional, and may contain wiki links or other formatting. Some of the parameters controlling thumb output can also be used here, specifically the ones that modify the file (as opposed to ones that control where in the page the image falls). For example, with multi-paged media like pdfs, you can use code like page=4.

The File: prefix can be omitted.

Zum Beispiel:

<gallery>
File:Example.jpg|Item 1
File:Example.jpg|a link to [[Help:Contents]]
File:Example.jpg
File:Example.jpg|alt=An example image. It has flowers
File:Example.jpg|''italic caption''
Example.jpg|on page "{{PAGENAME}}"
File:Using Firefox.pdf|page=72
</gallery>

is formatted as:

Mode parameter

MediaWiki version: 1.22

Starting in 1.22 we have an experimental mode parameter, taking options as follows:

  • traditional is the original gallery type used by MediaWiki.
  • nolines is similar to traditional, but with no border lines.
  • packed causes images to have the same height but different widths, with little space between the images. The rows in this responsive mode organize themselves according to the width of the screen.
  • packed-overlay shows the caption overlaid on the image, in a semi-transparent white box.
  • packed-hover is similar to packed-overlay, but with the caption and box only showing up on hover.
  • slideshow creates a slideshow of the images.

Zum Beispiel:

<gallery mode="packed-hover">
Image:Astronotus_ocellatus.jpg|''[[commons:Astronotus ocellatus|Astronotus ocellatus]]'' (Oscar)
Image:Salmonlarvakils.jpg|''[[commons:Salmo salar|Salmo salar]]'' (Salmon Larva)
Image:Georgia Aquarium - Giant Grouper.jpg|''[[commons:Epinephelus lanceolatus|Epinephelus lanceolatus]]'' (Giant grouper)

Image:Macropodus opercularis - front (aka).jpg|''[[commons:Macropodus opercularis|Macropodus opercularis]]'' (Paradise fish)
Image:Canthigaster valentini 1.jpg|''[[commons:Canthigaster valentini|Canthigaster valentini]]'' (Valentinni's sharpnose puffer)
Image:Flughahn.jpg|[[Image:POTY ribbon 2007.svg|25px]] ''[[commons:Dactylopterus volitans|Dactylopterus volitans]]'' (Flying gurnard)
Image:Fishmarket 01.jpg|''[[commons:Semicossyphus pulcher|Semicossyphus pulcher]]'' (California Sheephead)
Image:Pseudorasbora parva(edited version).jpg|''[[commons:Category:Pseudorasbora parva|Pseudorasbora parva]]'' (Topmouth gudgeon)
Image:MC Rotfeuerfisch.jpg|''[[commons:Category:Pterois antennata|Pterois antennata]]'' (Antennata Lionfish)
Image:Cleaning station konan.jpg|''[[commons:Novaculichthys taeniourus|Novaculichthys taeniourus]]''
Image:Synchiropus splendidus 2 Luc Viatour.jpg|''[[commons:Synchiropus splendidus|Synchiropus splendidus]]'' (Mandarin fish)
File:Psetta maxima Luc Viatour.jpg|''[[commons:Psetta maxima|Psetta maxima]]'' (Turbot)
File:Australian blenny.jpg|''[[commons:Category:Ecsenius|Ecsenius axelrodi]]''
</gallery>

Gives (mode: packed-hover):

Examples of the other modes:

mode="traditional"

mode="nolines"

mode="packed"

mode="packed-overlay"


MediaWiki version: 1.28

mode="slideshow"


Optional gallery attributes

The gallery tag itself takes several additional parameters, specified as attribute name-value pairs:

<gallery {parameters}>
{images}
</gallery>
  • caption="{caption}": (caption text between double quotes for more than a word) sets a caption centered atop the gallery.
  • widths={width}px: sets the (max) widths of the images; the default is 120px. Note the plural: widths.
  • heights={heights}px: sets the (max) heights of the images.
  • perrow={integer}: sets the number of images per row. 0 means automatically adjust based on width of screen.
  • showfilename={anything}: Show the filenames of the images in the individual captions for each image (1.17+).
  • mode={traditional|nolines|packed|packed-hover|packed-overlay|slideshow}: See section above (1.22+; 1.28+ for "slideshow").
The widths and heights parameters are taken more as suggestions than strict values for packed (and related) modes. Packed modes will adjust the width of images in order to make each row the same length.

Beispiel:

Coding:

<gallery widths=60px heights=60px perrow=7 caption="sunflowers are groovy">
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
File:Example.jpg
</gallery>

Row of images that will wrap to browser width

One way that works for a row of images with varying widths is not to use "thumb" or "left" or "none". If "thumb" is not used (and thus no captions) a row of images will wrap to the browser width. If necessary, narrow the browser window to see the images wrap to the next row.

[[File:Example.jpg|220px]]
[[File:Example.jpg|100px]]
[[File:Example.jpg|150px]]
[[File:Example.jpg|250px]]
[[File:Example.jpg|200px]]
[[File:Example.jpg|50px]]
[[File:Example.jpg|220px]]
[[File:Example.jpg|175px]]

Example.jpg Example.jpg Example.jpg Example.jpg Example.jpg Example.jpg Example.jpg Example.jpg

To wrap images of varying widths with captions it is necessary to use div HTML for an unordered list. Along with style="display: inline-block;". For more info and ideas see: Give Floats the Flick in CSS Layouts.

<div><ul> 
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|220px|Caption 1]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|100px|Caption 2]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|150px|Caption 3]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|250px|Caption 4]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|200px|Caption 5]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|50px|Caption 6]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|220px|Caption 7]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|175px|Caption 8]] </li>
</ul></div>
  • Caption 1
  • Caption 2
  • Caption 3
  • Caption 4
  • Caption 5
  • Caption 6
  • Caption 7
  • Caption 8

Some wiki farms do not have all gallery options (such as "widths"). Also, sometimes one wants varying widths for images in a row. Outside of a gallery, or the div HTML, it is impossible to have individual captions for images in a row of images that will wrap to the browser width. Try it and see. Nothing else using wikitext works correctly. Images will either overlap stuff on the right, or force a horizontal scroll bar.

Using a left float ("left") for some images, combined with "none" for some of the images, will not work consistently either, especially if there is also a right sidebar of images. Weird things will occur. At narrower browser or screen widths an image out of the row may appear far down the page after the end of the right sidebar of images.

Link behavior

By default an image links to its file description page. The "link=" option modifies this behavior to link to another page or website, or to turn off the image's linking behavior.

Alternatively, you can create a text link to a file description page or to the file itself. See Help:Linking to filesHelp:Linking to files.

Display image, link it to another page or website

Use "link=" option to link image to another page or website:

Clicking on the below image will take you to MediaWiki:

[[File:Wiki.png|50px|link=MediaWiki]]

Wiki.png

Clicking on the below image will take you to example.com:

[[File:Wiki.png|50px|link=http://example.com]]

Wiki.png

Display image, turn off link

Use "link=" option with no value assigned to turn link off entirely; the below image is not a link:

[[File:Wiki.png|50px|link=]]

Wiki.png


Requisites

Before using images in your page, the system administrator of your wiki must have enabled file uploads and a user has to upload the file. System administrators may also set the wiki to accept files from foreign repositories, such as the Wikimedia Commons. For server side image resizing it is necessary to have a scaler configured (such as GD2, ImageMagick, etc.).

Files at other websites

You can link to an external file available online using the same syntax used for linking to an external web page. With these syntaxes, the image will not be rendered, but only the text of the link to this image will be displayed.

[http://url.for/some/image.png]

Or with a different displayed text:

[http://url.for/some/image.png link text here]

Additional MediaWiki markup or HTML/CSS formatting (for inline elements) is permitted in this displayed text (with the exception of embedded links that would break the surrounding link):

[http://www.example.com/some/image.png Example '''<del>rich</del>''' ''<ins>link text</ins>'' here.]

which renders as: Example rich link text here.

If it is enabled on your wiki (see Manual:$wgAllowExternalImagesManual:$wgAllowExternalImages), you can also embed external images. To do that, simply insert the image's url:

http://url.for/some/image.png

Currently, embedded images cannot be resized, but they may be formatted by surrounding MediaWiki markup or HTML/CSS code.

If this wiki option is not enabled, the image will not be embedded but rendered as a textual link to the external site, just like above.
