I'm always looking for new free software on the Internet and although I already found an automatic wallpaper changer called Wallpaper Juggler I decided to give the wallpaper changer ScrollWall a try. It is always good to have some choice when it comes to programs, so that you can switch to the other program when one stops working suddenly for instance.
ScrollWall offers a very clean interface with only a few options to choose from. You can choose if you want to stretch, center or tile wallpapers that do not fit the monitor's resolution and select the frequency that you want the background images to change.
The option here is to either change the wallpaper automatically at startup or choose the amount of time before the wallpaper is changed. This can be anywhere from 1 second to 59 hours. You can add multiple wallpapers at once if they are in the same directory but it is not possible to add folders that contain wallpapers for instance.
The Wallpaper Juggler on the other hand lets youadd folders that contain wallpapers but is more limited when it comes to specifying the interval in which wallpapers should be cycled through on your system.
The Wallpaper Juggler needs about 10 Megabytes of RAM while Scrollwall eats away about 15 Megabytes. I'm not sure why the amount of RAM is that high in both programs.
The main difference that I can see is that Scrollwall lets you change the wallpaper at startup (but not after a set time if you choose this option). If you have a computer that does not have that much RAM you should use Wallpaper Juggler because it uses less of it. ScrollWall is said to work under Windows Vista while I was not able to find information about Wallpaper Juggler and Vista. (did not try both programs on Vista, only XP)
One last note. ScrollWall asks if you want to install the Delio toolbar during installation. This is not needed to run the program so I suggest you better not install it.
ScrollWall is a useful program if you want to change the wallpaper of your screen regularly automatically. It is easy to use and does not get in your way once you have configured it properly.
While it could use a couple of extra options, for instance the ability to load a folder full of pictures into the application, it is not really something that is too problematic to get around.
