Photo Stacker lets you choose a folder of pictures, and have those pictures randomly scattered across your desktop.
DIGITAL PICTURES
Digital pictures are PhotoStacker's specialty - using your personal photos to transform your desktop wallpaper into a dynamic and entertaining work of art! ...there is even a random setting enabling PhotoStacker to query random folders for digital pictures to use during wallpaper creation - helping to revive those lost Moments and providing a Pathway to begin exploring that folder on your own. HERE is PhotoStacker using locally stored digital pictures.
Picasa
PhotoStacker uses PicasaWeb to query openly licensed digital images on Google's photo system. With the capability to grab images from a particular person or explore the different image tags - Google's Picasa puts millions of photos at your fingertips and allows you to enjoy other's photos while providing a means to see more of their work. HERE is PhotoStacker using Picasa.
iTunes
Using the album art automatically downloaded by Apple's iTunes - PhotoStacker extracts this art and displays it as wallpaper with or without a CD case. Allowing you to visually see the current music stored on your computer - the experience becomes even more real when you can click on the album art and iTunes automatically plays it! HERE is PhotoStacker using iTunes.
FLICKR
Yahoo's Flickr allows PhotoStacker to access openly licensed images automatically - enabling PhotoStacker users to browse People, Groups, and Tags and display images related to the search. Each picture is also still tied to the original Photographer so by clicking on the displayed photo, PhotoStacker users will be provided with a direct web-link to that Flickr Member's photo allowing further exploration. HERE is PhotoStacker using Flickr.
AUTO-CHANGER
PhotoStacker's AutoChanger allows any one of the Picture Sources to be used in automatic wallpaper creation as often as every minute.
