What's going on with this file upload?

[Anon]

I have a file uploading script on my site and it's having problems handling specific pictures.

I asked for the user to "right click" on the image and select properties and send me a print screen. The file type of the image is "JPG File" not the normal "JPEG Image".

What's the difference and how can I go about fixing this?

What exactly is the problem? Are you filtering for JPEG and thus missing the JPG files?
