Alt link incase Go to deal doesn't work - http://www.wallpaperchanger.de/
Hi guys & gals thought I'd post this seeing as its a brilliant piece of software & invaluable to those of us who like their wallpaper changed regularly
It works with XP/Vista but Windows 7 is a 50/50 chance, it worked on my copy of W7 ultimate but not my mates (well it did work but it just kept losing the wallpaper list upon restart, alright for those who hardly restart)
This is better than the default wallpaper changer in Windows 7 for two main reasons, 1) It doesn't require Vista Home premium or better, 2) It looks in subfolders, unlike the default one which is limited to one folder & it refuses to look in sub directories (i have about 5000 different wallpapers so sticking them in one folder doesn't make it easy to scroll through)
Wallpaper Changer is a FREEWARE Windows 9x/NT/2000/XP wallpaper manager that can change your background images on every startup, once a day or at regular intervals. It features JPEG, PNG, GIF and BMP support. Several options are provided, including the ability to change your images in random order.
Your pictures can be automatically tiled, centered or re-sized to full screen. Wallpaper Changer can analyze your picture and will determinate the best matching background and the most readable icon caption color for every wallpaper you apply to your desktop. You can create, save and reload your collections of your favorite wallpapers. Simply add single pictures or whole directories via drag & drop from Explorer or search your hard drive for all supported graphics files.
Any questions feel free to ask & I'll do my best to answer
