I guess the simplest way to find out what's going on is to note down the
files that this isn't working for, and enter the corresponding URLs
directly into your browser (i.e.
http://example.com/image.php?ownerId=XXX&fileName=XXX...)
However, comment out the imagejpeg() line, and put in some diagnostic
output, i.e. echo out useful info at each stage of the script, to make
sure variables are what you expect them to be, and that functions are
being called successfully.
e.g.:
...
$fileData = @file_get_contents($filePath . $fileName);
echo "file_get_contents() " .
($fileData) ? "success" : "failure";
...
and so on...
