I thought I had found the solution for a shopping cart on my site. Everything is wonderful - but there is one big flaw. When the thumbnail image is clicked on - the big image opens on another page and to navigate back from there is hopeless. It would have been nice to have a popup or lightbox. I did notice on the demo that there is this effect and I seached the forums for how this could be attained, but there are no answers. A shame. For this one simple problem I can´t use this, otherwise good extension for my site.
