Hello,

It seems that we have missed out the option in the Theme Settings already available for the Pagination Dots under the Product Image instead of Thumbnail Images. We apologize for that inconvenience from our end.

Please once navigate to the Dashboard > Theme Settings > Single Product > Images > Thumbnails > in that you can find the option Pagination in main gallery > you can enable that toggle option and it will preview something like this on the Product page: https://woodmart.xtemos.com/theme-settings-tooltips/pagination-main-gallery.mp4

See the following Image for reference: https://snipboard.io/orYbAJ.jpg

So, instead of trying any Custom Code, please use the above told option on your Site in this regard.

Hope this helps !

Best Regards
