File must be a JPG or GIF type image (random contest help)

[Scream]

I'm getting this when i send in my pic:

ERROR : File must be a JPG or GIF type image. (ie. have the '.jpg' or '.gif' extension at the end of the file name in LOWERCASE letters). You submitted filetype: image/pjpeg

It is a .jpg, and no caps either. What's going on?

That happened to me for the negg contest. It didn't accept the entry no matter what I did.

I had this problem with the paint brush contest, just save it as a gif and it'll go through.
