My php pages are on Server1 and my images are on Server2 on same network (the folder on server 2 is accessed as a mapped drive R: on server1).
When I execute 'identify //server2/folder/image.jpg' from command prompt, it works fine.
But when I run the same from PHP, it does nothing.
What could be wrong?

did you specify the full path to identify or convert, etc. also for textual output you may need to add 2>&1
