Php converting jpegs to pjpegs: Help

Posted by "jnoyes" on 09/17/05 20:00

Can someone tell me why, or better yet how I can make sure that PHP doesn't
turn my non-progressive jpegs to pjepgs on upload? Using the code below, if
I upload a non-progressive jpeg, PHP tells me that the file uploaded
successfully, and the file is of type pjpeg. How can I avoid this problem?
