I have been selling on the web for a long time. There used to be a courtesy from buyers. I always post as many photos and as much info as I can in any ad. I think it' a seller's courtesy to provide all of the info and clear photos so that a buyer doesn't waste their time or yours. It's when you do this and the potential buyer asks for more info to not give the seller the courtesy of a response to say they want it or to say they will pass. Nothing more frustrating then a person say they will get back to you and then not have the courtesy to respond.
