Simple question about product images

hi, can anyone tell me where the settings are for the main image on the product page (not the large one in the popup), eg [url]Instant Demo - CS-Cart Multi-Vendor Demo Try Free for 15 days

i’ve looked at the thumbnail settings but they don’t seem to relate to the product image size. my product image is 150x200. whereas my product thumbnail settings are 163x218. (by the way, the product image that i uploaded is much bigger - 711x948).

any help would be much appreciated.

ok, you can ignore me. i’ve just realised what’s going on. i’m using the magic zoom addon and it’s controlling the size of the image.
