Here's a tip for windows XP users. If you want to save a DDDA picture as a screensaver/wallpaper,it couldn't be easier. This is all you have to do.
Firstly open any DDDA picture folder that you may have in your collection, then select a picture that you like, now select the 'Set as Desktop Background' in the pop-up menu that appears, and it's all magically done for you - it's as simple as that! When you get tired of looking at the same old picture move on to another one.
