How can I slow down picture frequency on screen saver?
I use an iPhoto smartfolder as slideshow for screensaver, but it shifts the picture every 2 seconds, which is far faster than I want it. About 30 seconds watch on each picture would be fine, Is there no way to change this setting on Mountain Lion?
