Foren / Cotonti / Support / Mime type for bmp is missing ??

This is incorrect, images should not be going through the mimetype.php check, they have a special check of their own.

Actually, I forgot why its like that, its due to php's lack of a imagecreatefrombmp function.
Place this in your datas/mimetype.php at the bottom, this will allow your bmp's to work.
