Hello,
I just moved my image uploader script from a windows server to linux. Somehow I guess php was grabbing the post variables automatically on the windows server.
Any way, my problem is that it is not reading the file on the upload page. It throws the error "Error: No File Specified". I tried putting $img1_name=$_FILES['img1_name']; then I was getting a file extension error.
