It would be nice if you would get a Camera of some sort & Take pictures & share them in-game.
When you take a Picture with your Camera, the client renders a small (maybe 320x280) image probably in compressed .jpg format & uploads it to the server, now you have an item called a \"Photo\" Which maybe can be placed in a Photo Album, Shared with others & maybe in the future put in a picture frame & hung on the wall of your Guild or House.
It would not have to be approved by mods because It\'s stuff people would already be seeing in-game. not exactly a screen-shot system but photos your Characters can share with each other.
