Boomer, this works fine now. I think there was a problem with a particular image I was testing it with. I tried a different image and the initial popup re-size now works.... wierd.
For v4 you just have to place
product_detailed_images.php in the root directory, rather than in the /customer dir.
A good extra feature on the popup, would be to have a indication of the number of detailed images available. eg. 1/3, 2/3, 3/3, or if there is only 1 or 2 detailed image available, remove the
<Previous and
Next> links respectively. Is this possible?
Thanks for the code!
