Have I found a bug in NextGen!?
I used [ngg_images gallery_ids="12" display_type="photocrati-nextgen_basic_thumbnails" order_by="rand()" number_of_columns="4"]
the bug I think I have found is that when you click the next button it shows the correct number of remaining images BUT as it random the images loaded are sometimes duplicates from the first page not the remaining unseen images!!!
Or is the problem in the short code?
