I used the instructions here....

https://www.zen-cart.com/tutorials/index.php?article=58[/QUOTE]

And it's working in a fashion. I can see multiple images on this product page...

http://www.fastbikegear.co.nz/index....roducts_id=338

But when I click on the fourth image displayed (which is a repeat of the first image) It opens in a new window rather than in a 'light box' like the first three images?

Can anyone tell me how I stop the fourth image (which is just a repeat of the first image) from showing on the product page or failing that how do I stop it opening in a new window?

I am using Zen Cart 1.38

Many thanks in advance.
