I don't think I would be on board with a picture, I could see it consuming a lot of resources, especially given how diverse some characters can be. Hairstyles, faces, skin tones, etc.

I would however think it fairly reasonable to have race/gender statues as furnishing items and then just use a Message Book-esque feature to have a short little memoir encapsulating their escapades. Just a simple fairly generic statue for each race and gender.
