Images for my Vault Dwellers

Hello fellow Mutants,

I’m building a Campaign in Roll20 with lots of Vault Dweller NPC’s and would like to give them all their own profile images and tokens.

I was thinking of using one of the Fallout game’s character creation sequences to make a custom profile image, then screenshot the image, and use that as the character’s image. This should work, but I’m wondering if there are any tools that let me do this without going into the game and screen grabbing.

Anybody know any tools for this that aren’t just AI generated images? (AI artwork makes my skin crawl)
