Replying to just let any others who are searching about these kinds of issue: In terms of my problem with twice duplicate thumbs produced by the dmfarrell code, I have no idea still why it was happening. It even did that with text. I replaced the liquid data call with an edited version of Jimmy Xiao code. I wont link it bc this reply will get swept into spam. Google Jimmy Xiao Lightgallery.
This post was stuck in the forum spam bin for about a week. I therefore had to find the solution elsewhere. Im disappointed in the inefficiency of this forum as I use several others with this forum tech and they work perfectly well without recklessly banning people’s posts. Sorry to say it really failed me.
Another post I tried that also got swept into spam - this one didnt have any links in it. These were NOT my first posts in this forum.
