Hi,
Let me see if I understand you properly… You are looking for a memory palace template that you can customize by inserting your own photos as locations? Or are you looking for a template with pre-made locations that you can fill with photos of the things you want to remember?
Not to be a sceptic but the effort in both of those ideas would be enormous!
Have you read the “how to get started guide?”. I’ll edit this post with a link. Creating a memory palace should be effortless!
