Do you ever insert pictures of the setting/area into a roleplay post to help players visualize/understand it? Do you commission these pictures, draw them yourself, or find them online? (You credit the artist, right?) If you find them online, where do you look for them? What do you do if the best available picture isn't exactly what you had, er, pictured? Do you typically only use them in the OOC or OP, or whenever the scene changes?
