I’m not aware of any way to make an image interactive like that. Perhaps you can design a solution using the regular map layout. This is how my map works:
Using the Glide Map layout, place a geocode pin in the middle of each region using the region name.
When someone selects a map pin, that region name pops up on the bottom.
When the user clicks on the pop-up on the bottom, they go to the detail screen for that region.
Please let me know what solution you ultimately find. For myself, I really need Glide to add “map clusters” as a feature as one zooms in on the map.
Good luck.
