That was something you could do in TS2, sort of, I think. Where you could upload your own photos, it could be of say, your pet, and a Sim with a high enough painting skill could paint them.
I really like that idea and it should come back.
I would like some different sliders. I would like some ear sliders, to make elf ears, and I would like some rear and hip sliders as well, but I want EA to provide me this, and not a mod creator. I know it sounds a bit silly, but I like EA sliders better, because I don't have to worry about how it will effect my Sims if those sliders are no longer updated by a mod creator, or that a person will need a mod to play with my Sims, if I were to use those sliders, assuming that person prefers a clean game. I know it sounds silly, but at least when EA provides it, all I have to worry about is having the latest patch for these uploads to work. Like changing one's makeup during the day.
