Installed imagehandler 4 on zencart 1.5.1. I used the install script. Install messages showed success when I went to admin section. All files installed and permissions are correct.

My problem is that all of my product images are on a dedicated server. When I modified the zencart config.php file to point the image directory to the server, it does pull the images correctly, but does not resize them.

Is imagehandler not able to resize images from an external server?
