Hi. Then I'm upload image.jpeg - everything ok, if I try upload image.jpg or image.JPG - zen gallery don't show it and don't create thumbnails. There problem? Thanks.

Can you clarify? Does image.jpeg work, or does it not work? Thanks.

image.jpeg - work. image.jpg or image.JPG - don't work.

Very weird... I would expect it the other way around. Can I see your gallery link?
