File analyst problem?

Hi,

I currently admin a free webhosting server. Recently we have found many users hosting tons of big JPEG images. However, theses images aren't porn related and aren't of good quality. I must also say that the same *Image* is repeated often if different file while having different size.

This sound really weird. I have tried to analyses the files with every tool I had, photoshop and other. I found nothing that should take all this space.

The 'file' utility in unix also reported that theses images were real jpeg:

: JPEG image data, JFIF standard 1.01, resolution (DPI), 36 x 36

I doubt this kind of image can take 450K of size. Do any of you know any file analyst program that could help me to determine what kind of files is this?

Thanks in advance...
