-The media galleries API allows you to access media files (images,
-video, audio) from the user's local disks (with the user's consent).
-</p>
-
-<p>
-Using the API, you can prompt the user for permission to access the media
-galleries. The permission dialog will contain common media locations for
-the platform and will allow the user to add additional locations. From those
-locations, only media files will be present in the file system objects.
-</P>
-
-<h2 id="manifest">Manifest</h2>
-<p>The media galleries API has two axes of permissions; the locations that
-can be accessed, and the type of access (read-only, read-write, add-files).</p>
-
-<p>On the location axis, specifying no location-type permission means that
-no media galleries are accessible until the user grants permission to
-specific media galleries at runtime using the media gallery configuration
-dialog. This dialog can be programmatically triggered.  Alternatively,
-specifying the "mediaGalleriesAllGalleries" permission grants access to all
-auto-detected media galleries on the user's computer. However, this
-permission displays an install time prompt indicating that the extension
-will have access to all of the user's media files.</p>
-
-<p>On the access type axis, the "mediaGalleriesRead" permission grants the
-extension the right to read files. This permission does not trigger an install
-time permission prompt because the user must still grant access to particular
-galleries, either with the "mediaGalleriesAllGalleries" permission or at
-runtime by using the media gallery management dialog. For example:</p>
-
-<pre>{
-  "name": "My extension",
-  ...
-  "permissions": [
-    <b>"mediaGalleriesAllGalleries"</b>
-    <b>"mediaGalleriesRead"</b>
-  ],
-  ...
-}</pre>
-
-<p>This set of permissions will trigger an install time permission prompt
-and let the extension read from all auto-detected media galleries on the
-user's computer. The user may add or remove galleries using the
-media gallery management dialog, after which the extension will be able
-to read all the media files from galleries that the user has selected.</p>
-
-<p>Currently "mediaGalleriesRead" is the only access type supported by
-this API. Read-write and add-file access with be implemented soon.</p>
