Product Info Display with add'l images relocated? Could Someone Explain Just How To.

I don't know if I am missing something or the steps just isn't there. I am trying to add additional pictures to my product info page. I have looked through all kinds of threads. None are clear. Now I feel I am somewhat knowledgeable about programming, so it's not like I am stuck on stupid lol. Could someone point me in a good direction, I was trying this Product Info Display with add'l images relocated add on but there isn't much info on how to properly install or use. Much appreciation to all that replay.

Here is my website, https://www.gemz4you.com maybe its a code issue?:censored:

As kobra said we can't see your product info pages.

Is the problem the location of the images, or can't you get them to show up at all?

If the latter:
