I need to add Pagination to my image gallery in my Wix website

I am looking to have something like a script /coding/software added to my Wix website i am building a website on the Wix platform,m right now. I have tried one way but it`s a right pain to sort.

it would be good i could use whatever you put together for me for another website i may build on Wix at a let date as well.

And need to add pagination to the image galleries i will be adding. And i will be adding a lot of images to my site. And need to break the numbers of images down to say 50 images only per page.

I have put a screenshot in with this job for you to see what i need to achieve.
