This Zen Cart add-on will give you the ability to check and see if you have an image set up for your products, but the image is missing from the server.  It will produce a report that shows the product name, model, path to and name of missing image and a link to go directly to the product to upload a new image.

NOTE:  This will only search for images in ONE directory - such as public_html/images.

Works with Zen Cart Versions:  1.5.0, 1.5.1, 1.5.2, 1.5.3, 1.5.4, 1.5.5
