DarkAngel:
ok, went to your store and is this a purchased template? First time seeing the additional images at the top of the page vs the bottom of description page.
I tried the one on http://www.mythreejewelz.com/index.php?main_page=product_info&cPath=1&products_id=4
and the first image gives no lightbox, the other two do but they do not go from one to the other like they should, could you post your settings in admin?
The template is Avonlee_Contempo, a free offering from Picaflor-Azul. Anne did a great job modifying the page so that all images showed on the same line instead of having secondary location below the description. (A request from the store owner.)
I clicked on the link as you have it and was able to get the lightbox to work on all three images. Can you tell me your browser and any other information as to the time you could not get the first one to work. I'll try to duplicate and find the cause.
Be aware that the problem with the prev/next icons appeared before we modified the template to what you see.

These are the settings under lightbox.
Once again, all we are trying to do is get the next/prev buttons to stay obvious (not hide).
Thanks for your assistance. It still has me baffled.
