Hi. I have Mac OS X 10.4.11 and I am getting into the whole wallpaper changing thing now. I have a folder of photos that the wallpaper uses to change every 5 seconds. I don't want it to change every 5 seconds, I want it to change every 10 seconds, but it's not an option, it goes from 5 seconds, to 30 seconds, to a minute. Can I edit a file or something to make it change every 10 seconds or another custom time? Thanks!
