Image Gallery Thumbnails

I am using the most recent WP version and most recent Woo Commerce version. The customer is using the most recent version of Avada theme.

I uploaded and display 8 images in the gallery showing up within product details page.

Under the main image are four thumbnails displaying. I prefer just four initial images because many of the products will have up to 30 available images.

However, the potential for confusion as to how many images exist, so I want to add a TEXT STATEMENT informing the viewer to click on any of the gallery images to display all images in the resulting jquery pop-up.

What folder/file/path should I look for and modify to place a text statement below the gallery thumnails to inform viewers how to click and see all available gallery images?
