if you limit in your preference image size viewed in [[Image:]] page the full
size url doesn't work as expected (see code ImagePage.php line 45 $url is
overwritten later when calling createThumb(). Patch joined. A side effect of
this patch is to not call createThumb() twice when image size is constrained by
both with and height. (Note this bug is unrelated to Brion recent fix about $max
et $height uninitialized when user preference about max image size is not set)

Bug easy to reproduce, set your user pref to 320*200, go to the above url click
on the link view full image size.
