I am in the process of getting a cart up and going (1.5) and I have a base image for my products, however I was wanting the main image to be replaced by the attribute image - based on which attribute is selected.

Can someone please advise which way is the best to go about it?

I am after what this addon can do...
Attribute image replaces main product image on sel (http://www.zen-cart.com/downloads.php?do=file&id=699), but that addon is 4 years old now...
Ajax Image Swapper seems to do it too... (http://www.zen-cart.com/downloads.php?do=file&id=564), and this one is 2 years old.

So surely this is something that is more widely used since then?? I was hoping to not need to go all through installing the mod if it is not what I am needing specially if it is not compatible with 1.5...

Does Zen-Lightbox have the ability to replace the main product image on the product info page with the image from a selected attribute? or is there a more appropriate addon (or way to do it within already builtin that I am just not seeing?)

Any help would be greatly appreciated!!! Thanks!
