Howdy Dan,
Welcome to our support forums and thanks for reaching out to us.
Interesting customization here, I think we’ve never heard of a similar request!
First place to start working on this is our Themer’s guide. Have you checked that out and understood it?
The process of replacing the links should be fairly simple, a quick template override should be enough. Now regarding the map + photo views combination, that can be a bit trickier. I guess the way to go would be to build the ‘photo display’ in map view and not the other way around, as they way map view works is a bit harder to replicate.
Please let me know if you could go through the themer’s guide and understand the process works, that way I can point you to the right direction,
Best,
Nico
