image handling code in update_product.php

[lhungil]

I've been fighting with developing procedures for support personel on resizing images for zencart ...

This code requires one to add the relevant defines in a new file such as "/admin/includes/extra_configures/image_handler.php"... This method would require the following on the server: ImageMagick binary files and libraries installed, PHP exec enabled (and allowed to call the ImageMagick binary), and knowledge of the installation location / path for the ImageMagick binaries.

Here is a link to the 3rd party plugin Image Handler v4 for Zen Cart 1.5.x if you want to give it a try (it works well in my experience). Make sure to create a backup of your site and read the readme before installing or using IH4.
