Ive created an uplaod script in php that takes a file, resizes it, and creates a cropped square thumbnail. The script itself seems to work fine.

However, when i tried to upload an image through firefox, on clicking the submit button the browser shows the loading animation, but it never calls the script, it just stays on the current page. If dont upload an image, then the script can be found and is run.

I tried in safari, and i dont get the same problem, i can upload an image from the form, it will process it and take me the correct page.

Ive tired just calling a basic script from the form, it just prints out the $_POST and $_FILES, and i get the same result, if an image is present, it wont get to the script, if no image is present, it runs fine.

Im just wondering if anyone has any idea whats going on?
