This way I can write a letter saying something like:
“””
You open the letter that's addressed to Withmore.
It reads:
This is Jane Brads. She is a baka. Beat her down on sight.
The letter has been signed by Bob
“””
Then ‘put photo on letter’. Then, when you read the letter you see:
“””
You open the letter that's addressed to Withmore.
You see:
A photograph of Jan
The six-foot-three woman before you has pale skin and seems exceptionally frail.
Jane is holding a beer.
Jane is in excellent condition. She is a little dusty.
It reads:
This is Jane Brads. She is a baka. Beat her down on sight.
The letter has been signed by Bob
“””
Later on you can ‘remove photo from letter’ to get it back. It could also take a skill/stat check to remove the picture without destroying it, the letter or both. So people with the right skill/stats might be able to mess with them (change the picture on a letter) should they have access.
Same concept with flyers. RP wise you are actually attaching the picture to the paper and removing it.
