Answer 1

The PHP script probably doesn't know where to find these things you're referring to in the exec command. When you run this from the command line, the shell will look for them in the directory you are in at that point in time; but when you run it from PHP, it probably defaults to the PHP dir and not the specific dir in which your files are. So write out the full path.

Answer 2

you should enter fullpath to "convert" and may be files.

err 127 - file not found

Answer 3

It looks like the 'convert' binary isn't in any of the directories on the PATH PHP is using. You could try using the full path, e.g. /opt/local/bin/convert or whatever the path is.

You could also modify the PATH used by PHP (but I don't know how).
