Hello yellow1912,
Is it possible to let the additional images just show in the lightbox, but not the thumbs below the main image?

Because I have to control my info page to 700px height. So I have to hide the normal additional images' thumbs.

I have: item_LRG.jpg, item_01_LRG.jpg, item_02_LRG.jpg in the images/large folder already.
And just item.jpg in the image folder. But the lightbox didn't have next image tab shown...

Then I put item_01.jpg, item_02.jpg to the image folder too, and turn off the additional image in admin panel. The lightbox also no next tab shown.

Wait and thanks for your help.
