Willkommen auf der Hilfeseite für den Medienbetrachter, einen neuen Multimedia-Browser für die Wikimedia-Wikis.

Diese Seite enthält häufig gestellte Fragen über zentrale Funktionalitäten dieses Projektes.

What is Media Viewer?
Media Viewer is a new multimedia browser that aims to improve the viewing experience on Wikipedia, Commons and MediaWiki sites. It lets you view images in larger size, with useful information about their authors, license terms and other metadata. It also offers a number of tools for sharing, embedding and downloading media files.

Das Tool wurde vom Multimedia-Team der Wikimedia Foundation entwickelt. Um mehr über den Medienbetrachter zu erfahren, lies unten weiter oder besuche die Produktseite auf MediaWiki.org.

Warum den Medienbetrachter?
Der Zweck dieses Tools ist:
 * ein verbesserte Multimedia-Erfahrung zu bieten
 * Bilder in größeren Abmessungen anzeigen, direkt auf der Seite, auf der du dich befindest
 * Verwirrung zu reduzieren, wenn ein Benutzer auf Vorschaubilder klickt

Der Medienbetrachter ist für alle Benutzer von Wikipedia, Commons und anderen MediaWiki-Seiten gedacht: Dies schließt sowohl Leser und neue Autoren als auch erfahrene Benutzer ein. Das Tool wurde erstellt, um gelegentliche Nutzer mit einer klareren Media-Erfahrung zu konfrontieren und sie im Laufe der Zeit einzuladen, mitzumachen, zu Bearbeiten und die Dateien weiterzunutzen.

How does Media Viewer work?
When you click on a thumbnail in an article, a large version of the image is shown, for a more immersive experience. Media Viewer fills your browser window with a ‘light box view’, right over the page where you clicked.

From here, you can access a number of features:
 * view more information
 * view images in full-screen
 * view original images in full resolution
 * browse through collections of images
 * share, embed or download an image
 * learn more about an image and its license
 * go to the file page to edit or discuss an image
 * close Media Viewer
 * disable Media Viewer

Lies unten mehr über diese Funktionen.

How can I bypass Media Viewer?
If you need to bypass Media Viewer to access its file description page directly, simply press one of these keys when clicking on a thumbnail:
 * shift-click - opens the page in a new window
 * command-click - opens the page in a new tab
 * control-click - shows a menu of options

How can I turn off this feature?
To disable this feature, open the information panel below any image in Media Viewer, then scroll down to the bottom and click on "Disable Media Viewer". From now on, images will no longer open in Media Viewer: clicking on thumbnails will take you to the file description page on Wikimedia Commons or other file repository. This disable feature works for registered users (using a site preference), as well as unregistered or 'anonymous' users (using a file stored locally on your computer).

If you are a registered user, you can also disable Media Viewer in your "Preferences": select the "Appearance" section, and uncheck this option under "Files":  '[  ] ’. Once you click "Save", images will no longer open in Media Viewer for your account on that site.

If you change your mind and wish to re-enable Media Viewer, follow the instructions below.

How can I re-enable this feature?
If you have turned off Media Viewer and wish to re-enable it, visit any image description page on the site where you wish to use this tool. Then click on the "Expand View" button below that image, which will open it in Media Viewer. Then scroll down to the bottom of the information panel below the image, and click on "Re-enable Media Viewer”. This re-enable feature works for registered users (using a site preference), as well as unregistered or 'anonymous' users (using a file stored locally on your computer).

If you are a registered user, you can also re-enable Media Viewer in your "Preferences": select the "Appearance" section, and check this option under "Files":  '[  ] ’. Once you click "Save", images will open in Media Viewer again for your account on that site.

How can I close Media Viewer?


You can close Media Viewer in a couple different ways:
 * click on the ‘X’ button at the top right of the Media Viewer panel (see thumbnail to the right)
 * press the ‘escape’ key on your keyboard

In einigen Fällen kannst du auch die "Zurück"-Schaltfläche des Browsers verwenden, um auf die vorherige Seite zurückzukehren.

How can I view more information?


Der Medienbetrachter zeigt grundlegende Information über das angezeigte Bild direkt am unteren Bildschirmrand. Dies schließt den Dateinamen, den Autor/Quelle sowie Lizenzinformationen ein.

For more information, simply scroll down to see a ‘metadata panel’ that includes more details, such as: image description, where the file is stored, who uploaded it, when it was created or uploaded, etc. (You can also click the arrow icon top or down on your keyboard to see this panel.)

If you would like even more information, click on the link to Wikimedia Commons or other file repository to view or edit its file description page.

How can I browse through a collection of images?


To browse through all the images in a collection, you can use the Next and Previous arrow buttons, which appear to the left and right of the image in Media Viewer (see thumbnail to the right).

A collection can include all the images in an article, a gallery or a category page. You can also use the left and right arrow keys on your keyboard for this feature.

How can I view an image in full-screen?


To see an image in full screen, click on the full screen button at the top right of the Media Viewer panel (its icon features two opposing arrows - see thumbnail to the right).

Dies zeigt ein Bild groß über den gesamten Bildschirm an, nicht nur im Browserfenster. Diese Vollbildansicht ist aufgeräumt, sodass man sich auf das Bild fokussieren kann. In diesem Modus werden die Bedienelemente automatisch ausgeblendet und der Dateiname zusammen mit dem Autor/Quelle/Lizenz erscheint erst, wenn du am die Maus an den unteren Bildschirmrand bewegst.

To exit full screen mode, you can click on the same button to return to the light box view — or select the close ‘X’ button to exit Media Viewer.

How can I view the original image in full-resolution?
To see the original image in full-resolution, click on the original image button at the bottom right of the Media Viewer panel (its icon features a landscape in a frame - see thumbnail to the right).

This will open the original image in its largest size, on Wikimedia Commons or the file repository site where it was first uploaded. You can then use your browser zoom feature to examine details of the image, or right-click it to use this file in a variety of ways. In this view, the Media Viewer controls disappear completely, so you can interact the image directly.

To view the image in Media Viewer again, simply click the 'back' button in your browser.

How can I view images in different sizes?


To view images in different sizes, click on the ‘Use this file’ button (the curved arrow icon at the lower right corner of the screen - see thumbnail to the right). This opens the ‘Download' panel, with the original image size pre-selected.

Then click on 'View in browser' below the green button to open the file at that size, in a separate tab.

To pick a different size, click the green down arrow button and select the size that best fits your needs (e.g. Small, Medium or Large).

How can I download an image?


To download an image, click on the ‘Use this file’ button (the curved arrow icon at the lower right corner of the screen - see thumbnail to the right). This opens the ‘Download' panel, with the original size pre-selected. Click on the green button to download the original file, using your browser’s tools.

To download an image in a different size, click the green down arrow, where you can pick the size that best fits your needs (e.g. Small, Medium or Large). You can also preview any of these sizes, before you download: click on 'View in browser' below the green button to open the file at the selected size in a separate tab.

Please check the license terms of a file before downloading it for your use, to confirm that this use is covered. Also, please include all required credits and links to comply with those terms: these credits are now included in the Embed panel, where you can copy and paste them for your purposes. They will soon be available in the Download panel as well.

How can I share an image?


To share images you find in Media Viewer, click on the ‘Use this file’ button (the curved arrow icon at the lower right corner of the screen - see thumbnail to the right). Then click 'Share'. This will show a link to the selected image, which you can copy and paste to share it with your community. Note that for now, this link will open the image in Media Viewer on its file repository page (e.g. Commons), not on the article where you found it.

How can I embed an image on another page?




To use an image on another wiki page or on other web sites, click on the ‘Use this file’ button (the curved arrow icon at the lower right corner - see thumbnail to the right). Then click on the 'Embed' tab. This will show the code needed to display the selected image, which you can copy and paste into your page’s code.

Um ein Bild auf einer Wikiseite einzubinden, wähle "Wikitext". Für die Einbindung auf einer standardmäßigen Webseite verwende "HTML". Meist ist die benötigte Namensnennung und Lizenzinfo zusammen mit der zugehörigen Verlinkung bereits im HTML-Code enthalten.

Mit der Größenauswahl kannst du die optimale Bildgröße für deine Seite auswählen. Du kannst natürlich auch die Breite und Höhe direkt im Code ändern.

Please check the license terms of a file before embedding it on a page, to confirm that this use is covered. Also, please include all required credits and links to comply with those terms.

Wie kann ich herausfinden, ob ein Bild weiterverwendet werden darf und was die Lizenzbestimmungen sind?


Viele der Bild sichtbar im Medienbetrachter können frei weitergenutzt werden, solange du Hinweise bereitstellst im Rahmen der Lizenzbestimmungen des Bildes. Beispielweise sind einige Bilder lizenziert unter Creative Commons terms (z.B. CC-BY oder CC-BY-SA). Andere sind im Public Domain, Gemeinfrei oder stehen unter einer anderen freien Lizenz.

Um herauszufinden was diese Lizenzbestimmungen bedeuten, klicke einfach auf den Link zur Lizenz neben dem Bildtitel. In einigen Fällen werden dann die Lizenzdetails im Metadatenabschnitt angezeigt. In anderen Fällen wirst du zur Bildbeschreibungsseite am Dateiablageort weitergeleitet, wo du mehr erfahren kannst.

If an image has special licensing terms or requires special credits or permissions, a ‘view terms’ link will be added next to the image title. Clicking it will show the permissions details and special requests from the author or source.

How can I edit or discuss an image?


To edit, curate or discuss an image, you need to go to its file description page (e.g. Wikimedia Commons or other repository).

You can do this by clicking on one of these buttons:
 * the ‘file page’ icon - at the lower right corner of the screen (e.g. Wikimedia Commons or 'W' logo - see thumbnail to the right).
 * the ‘Learn more’ link - in the right column of the information panel, scrolling down below the image.

How can I link to an image from wikitext?
You can use.

How can I disable Media Viewer for unrelated images?
Sometimes, Media Viewer displays images that are confusing for our users or are not suitable for viewing with this tool. If necessary, editors can prevent these images from appearing in Media Viewer, using one of the methods below.

(please only use this method to mark elements in articles that are considered not to be part of the proper content of the article: annotations, maintenance templates, navigation links, media controls, etc.)
 * For 'metadata' images that are not related to the page's topic (e.g. small icons, flags): you can disable Media Viewer for these files by adding this "metadata" class around their image tag:

(please only use this method to mark images that cannot be viewed effectively in Media Viewer because important details are hard to view with this tool; this method is intended for special cases, not for widespread use)
 * For other images that are not 'metadata' files, but do not display properly in Media Viewer (e.g. maps or diagrams with unreadable labels): you can disable Media Viewer for these files by adding this "noviewer" class inside their image tag:

Which platforms does Media Viewer support?
For this first release, Media Viewer now works on most modern web browsers for desktop computers: Chrome, Firefox and Safari's latest stable versions -- as well as Internet Explorer versions 9 and above. At this time, Media Viewer does not work on IE8 and below, and it is disabled for mobile devices. In future releases, we plan to provide a mobile version of Media Viewer, as well as wider browser support on desktop platforms.

Which file formats does Media Viewer support?
For this first release, Media Viewer only supports the most widely used image file formats (e.g.: JPEG, GIF, PNG, TIFF, SVG). In future releases, we will add support for PDF, audio, video and other file formats.

How can I report a technical issue?
We welcome bug reports from our community. If you find a technical issue, please [//bugzilla.wikimedia.org/enter_bug.cgi?product=MediaWiki%20extensions&component=MultimediaViewer file a bug here on Bugzilla].

Da Bugzilla nicht gerade einfach zu benutzen ist, kannst du dein Fehlerreport auch auf dieser Diskussionsseite melden, wenn möglich bitte inklusive Screenshot und Angaben zum verwendeten Browser und Betriebssystem.

Bitte überprüfe jedoch vor dem Melden eines Fehlers, ob nicht bereits in [//bugzilla.wikimedia.org/buglist.cgi?resolution=---&component=MultimediaViewer dieser Liste der bekannten Fehler] ist.

How was Media Viewer tested and released?
Media Viewer was tested extensively for over seven months by tens of thousands of users around the world, starting in November 2013, as part of the Beta Features program. This allowed users to enable Media Viewer long before it was released on their sites, by clicking on the small 'Beta' link next to 'Preferences' in their personal menu. We invite you to

After addressing key issues identified by our testers, Media Viewer v0.2 was gradually released between April and June 2014. Local deployments took place on different sites every week, through the middle of June, 2014, when this feature was enabled by default on all wikis hosted by the Wikimedia Foundation.
