picture uploading problem

[programmerhead]

I've set up a script on my site that allows for users to upload their own pictures to the server. But for some reason, ever one of the pictures turns out just blank. The size/dimensions of the pictures are correct, but the actual picture isn't showing up. Anyone have any clue why I might get this problem?

What webserver?
Where are you putting the files, are they readable as images by the webserver?

Apache does some nice stuff with image files in the cgi-bin directory [Why, I'm not so sure, but someone may enlighten us ...]
