Suggestion:
You can't really just get a photographic memory. You're born with it or not.
However you can enhance your memory ability so it links with a photographic memory by practising. You can try looking at text, pictures and trying to draw or write what you remember. Just practice and it'll get better and better. But this can be linked with memory games where you try to link things together, like trying to remember numbers by making a story with them.
Hope this helps
