Welkom op de hulppagina voor Mediaviewer, een nieuwe multimediabrowser voor de Wikimedia-sites.

Op deze pagina staan veelgestelde vragen over belangrijke onderdelen van dit project.

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.

Deze tool is ontwikkeld door het nieuwe multimediateam van de Wikimedia Foundation. Zie deze productpagina op MediaWiki.org om meer te weten te komen over Mediaviewer.

Waarom Mediaviewer?
De bedoeling van deze tool is om:
 * Een rijkere ervaring van multimedia te bieden
 * Afbeeldingen in een groter formaat weer te geven zonder dat je de website hoeft te verlaten
 * Minder verwarring te krijgen als gebruikers op afbeeldingen klikken

Mediaviewer is er voor alle gebruikers van Wikipedia, Commons en andere MediaWiki-sites, waaronder lezers en nieuwe gebruikers en ook ervaren gebruikers. Deze tool is ontwikkeld om gebruikers met deze kijkervaring meer te boeien en om ze dan uit te nodigen om bij te dragen, pagina's te bewerken en deze bestanden opnieuw te gebruiken.

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

Zie hieronder voor meer informatie over deze mogelijkheden:

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 sommige gevallen kun je ook op 'Terug' of 'Vorige' klikken in je browser om terug te gaan naar de pagina waar je Mediaviewer opende door op een afbeelding te klikken.

How can I view more information?


Mediaviewer toont onderaan het scherm basale gegevens over de afbeelding die je bekijkt, waaronder de bestandsnaam, de auteur en/of de bron en ook informatie over de licentie.

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).

Zo wordt een grote afbeelding over het hele scherm getoond, niet alleen in het venster van je browser. Dit is een overzichtelijke weergave waarmee je alleen de afbeelding tevoorschijn kan halen. In deze weergave zie je alleen de knopjes, de bestandsnaam en de auteur/bron/licentie als je met je cursor over de afbeelding gaat.

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.

Selecteer 'WikiText' voor de code om een afbeelding op een wikipagina toe te voegen. Selecteer 'HTML' voor de code om een afbeelding op een standaard webpagina toe te voegen. De vereiste naamsvermelding, licentievoorwaarden en bijbehorende links staan in de HTML-code.

Je kan zelf de gewenste grootte van de afbeelding selecteren. De afmetingen van de afbeeldingen zijn ook in de code zelf aan te passen.

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.

Hoe weet ik of een afbeelding mag gebruiken en wat de licentievoorwaarden zijn?


Veel van de afbeeldingen in Mediaviewer kunnen vrij worden hergebruikt, mits je aan naamsvermelding doet en je aan de licentievoorwaarden houdt. Sommige afbeeldingen hebben een Creative Commons-licentie (bijv. CC-BY of CC-BY-SA). Andere zijn publiek domein of hebben een andere vrije licentie.

Klik op de licentielink naast de bestandsnaam om de licentievoorwaarden te bekijken. In sommige gevallen worden de licentievoorwaarden op het 'metadata'-tabblad weergegeven. In andere gevallen ga je via deze link naar de bestandspagina, waar je meer te weten kan komen over de licentie.

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:

If you have questions or comments about these methods, please join this discussion.

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].

We weten echter dat Bugzilla geen eenvoudig systeem is om te gebruiken; je kan het probleem ook aangeven op deze discussiepagina, met een screenshot en informatie over je browser en besturingssysteem.

Voordat je een melding maakt, kun je eerst bekijken of het probleem niet al is [//bugzilla.wikimedia.org/buglist.cgi?resolution=---&component=MultimediaViewer gerapporteerd]. Als het probleem al is opgelost, kan je Mediaviewer uitproberen op deze testpagina op MediaWiki.org, waar nieuwe functies een week eerder worden uitgebracht dan op de andere wiki's.

How can I discuss new features for this tool?
We would like to know what you think of Media Viewer and invite you to participate on this discussion page.

Wereldwijd hebben tienduizenden gebruikers tijdens de ontwikkeling geholpen met het testen van Mediaviewer. Er is een overzicht van de feedback die zij hebben gegeven om de tool te verbeteren. Veel van hun suggesties worden nu doorgevoerd als onderdeel van ons huidige cyclusplan.

Waar vind ik technische gegevens over Mediaviewer?
Zie deze twee extensiepagina's voor meer technische informatie over deze tool: MultimediaViewer en CommonsMetadata op MediaWiki.org.

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.

For more information, check out this release page.

What new features are being planned for Media Viewer?
Er worden geen grote veranderingen meer ontwikkeld voor deze eerste uitgebrachte versie. We overwegen meer functies voor de later uit te brengen versies en we bereiden op basis van feedback van de gemeenschap ontwerpen en specificaties voor op deze pagina.

To prepare for future releases, we would love to hear which of these features seem most important to you. If you have any suggestions for improving this tool, please let us know on this discussion page.
