Sorry for cluttering this forum with so many questions and issues.
I’m new to this, and I get stuck every now and then. This forum is a blessing!
Ok. Here it goes:
I added a light box to the Product template (e-commerce).
I set it up so that it has room for 4 thumbnails below the main product image.
When the user clicks the main image or one of the thumbs, a popup window is triggered, with an enlarged image and slider arrows to the side let the user go through the four (enlarged) images within the popup.
No popup. When clicking on the thumbnails the main/large image is swapped and shows (a larger version of the) image of the thumb clicked.
How can I achieve that?
