gennarof: this will remove the duplicate, execute in SQL Patch area of X-Cart.
Code:
DELETE FROM xcart_modules WHERE module_name LIKE "PHPSS_Dynamic_Images" LIMIT 1;
mpgyvr: I just upload 1 large image to my product's thumbnail, that same image is used for product listings or the actual product page itself. That way, there's only one original image, and it is resized as needed for each area that the image is displayed (whether product page or product listings). Also, if you haven't already, I suggest you implement the how-to for enhancing Dynamic Images further, as it gives you a nice pop-up effect to view your full-size image. (the link should be on the first page of this thread, or you can just visit my forums directly to find the thread)
