Hello,
I'm having problems with the imagecreatefromjpeg() method. No matter what I do I can't get this method to work.
I've read that you have to manually change directories before you try to load the image - didn't work.
I've read that you need to use a URL - didn't work.
I'm beyond frustrated here... ANY HELP YOU CAN PROVIDE WOULD BE GREAT.
I'm running Fedora 4 full version.
Please HELP!!
