I am using ZenCart version 1.3.9g, Patch 1.
The site was upgraded from 1.3.9a.
The only addon I'm aware of is Image Handler 2.
The site uses a template.
I have searched and trolled the FAQs, Tutorials and Forums for hours.
The problem began when I started maintaining my customer's site.
Transactions are working fine and the store is live.


I've read the documentation that comes with the Image Handler 2 zip file and some things I found on the web.

Is it correct that the large version of the image is not modified by Image Handler, only the medium and small?

I'm seeing something strange. If there is an image for a product which is 600 x 600 px, when you click "Larger Image" on the product detail page, it displays at 600 x 600 px. However, in Admin - Tools - Image Handler2, the large size says it should be 550 x 550 px. The small and medium images display at the sizes shown in Image Handler.

How is the large size determined? How does Image Handler take an image that is 600 x 600 px and decide it should be 550 x 550 px? And why isn't is showing up that way when you click "Larger Image"?

Thank you in advance for any insights you can share.
