Thanks again, Dr. Byte! This PHP script worked perfectly.

I see that FIRST of all, I had no else statement, so even if I was otherwise correct, only half the desired result would obtain.

But additionally, Dr. Byte also didn't check for the file itself, but rather a string.

Can anyone simpy tell me..is the 'products_image_large' string the name of the file Zen Cart designates as the 'large image' that will display if the popup feature is on? In other words, does $products_image_large sometimes contain the name of a file that is NOT a large file, but just the base image file in /IMAGES/ which is then handled as such by zencart?

I notice that without 'popups disabled if no large photo' and no large photo is present, ZC will display a smaller image.

I am trying to understand this, Im new to PHP....



I understand that the IF (strstr statement is checking the $products_image_large string.....is it checking to see if the 'large/' subdir is part of the string? (as Im guerssing it would be if a large photo is present)

I am trying to understand this all a bit better....thanks in advance!!!!!!!!!
