I`m missing the setting to disable the changing option in full screen applications like games. But in overall it`s good. ;]

I used to use wallpaper spinner to change my wallpapers. i have 3,950 wallpapers. the problem with that program is that it would form patterns and use only about 100 or so pics from the folder. plus i had to manually add them. i stumbled on this program when i was looking for an alternative. it has features that allow it to only display a picture once and then when you use all the pics from a folder it will automatically start from the beginning again even if you shut the program down and start it up again. this solves the problem of forming patterns. and it uses them from a specified directory you set so you don't have to go through the pain in the but of manually loading them your self. another great plus is that you can set it to save and apply the selected settings when you start the program. im using windows xp pro with sp2 and i have not had any problems at all. overall im very happy with this program because it solves the problems that other programs have.

If you are looking for dynamic wallpapers your search has ended. This software is awesome! I'm using it in 3 different computers, with Windows ME and XP with no problems at all.
I love it ;)
