Hi Dave,
Perhaps what you should do to set $imageFile = "/images/image.jpg"
since I would assume, whatever your Document_Root is, 'images' is a
sub-directory to it.
I.e.: if your servable document directory is something like
"/vhome/tokyocomedy/all_your_files_are_here"
then
"/vhome/tokyocomedy/all_your_files_are_here/images/image.jpg" is where your
image.jpg file is.
Also, check using <?php phpinfo(); ?> where the $_SERVER['DOCUMENT_ROOT'] is
(under 'PHP Variables' section) and note where tempfiles are uploaded to as
well, if you're uploading.
HTh,
Andre
