[Mediawiki-api] Image properties

[Magnus Manske]

Hi,

IMHO the function that is missing the most in api.php is image
properties (width, height, size, media type, etc); the equivalent of
imageinfo on query.php.

When this is added, it might be nice to get information about the
thumbnail name as well, with a placeholder for the thumbnail width.

Also, one might want to think of making "file" an equivalent to
"image", so that "image" can be abolished later. Finding oggs in your
"image" list can be quite surprising otherwise :-)

So far my list of demands to be solved today ;-)

Cheers,
Magnus
