Alan, on a Netbook even your variant can be deadly. It depends how the folder is configurated. If it is set to details: good chance for ok, if it is set icon: good chance for ok, if it is set to small, medium or big picture it can freece the system. It doesn't happen necessarily, but it can happen. I had this twice as I was using Netbooks for my 24/7 "server". Well, there were 7000+ pictures in the folder at the time.
