<para>The default is 3 (front cover). There may only be one picture each of type 1 and 2 in a file.</para>
<para>MIME-TYPE is mandatory; for best compatibility with players, use pictures with MIME type image/jpeg or image/png. The MIME type can also be --&gt; to mean that FILE is actually a URL to an image, though this use is discouraged.</para>
<para>DESCRIPTION is optional; the default is an empty string.</para>
<para>The next part specfies the resolution and color information. If the MIME-TYPE is image/jpeg, image/png, or image/gif, you can usually leave this empty and they can be detected from the file. Otherwise, you must specify the width in pixels, height in pixels, and color depth in bits-per-pixel. If the image has indexed colors you should also specify the number of colors used. When manually specified, it is not checked against the file for accuracy.</para>
<para>FILE is the path to the picture file to be imported, or the URL if MIME type is --&gt;</para>
<para>For example, "|image/jpeg|||../cover.jpg" will embed the JPEG file at ../cover.jpg, defaulting to type 3 (front cover) and an empty description. The resolution and color info will be retrieved from the file itself.</para>
<para>The specification "4|-->|CD|320x300x24/173|http://blah.blah/backcover.tiff" will embed the given URL, with type 4 (back cover), description "CD", and a manually specified resolution of 320x300, 24 bits-per-pixel, and 173 colors. The file at the URL will not be fetched; the URL itself is stored in the PICTURE metadata block.</para>
