Like Winamp, Bionix Wallpaper gives you the posibility to gather images from all over the hardisk in one playlist, without changing their physical location.
Also, like Winamp, BioniX Wallpaper cycler has playlist navigation, which permits you to go back and next through the images.

The images can be stored in different directories, on different harddisks, even on different computers.
Also, you can make multiple tematic playlists and switch between them whenever you want to. It is easy to interact with the playlists through "Playlist Editor" or "MiniList". This wallpaper cyler supports more then 50.000 image files in one playlist.
BioniX associate itself with the palilist files (‘BIO’ files). This means that the wallpaper cycler will start automaticaly if you doubleclick a BIO file.
BioniX Wallpaper has in adition to the well known tile / stretch / center functions, 2 new smart functions:
* smart stretch (if some of your pictures are bigger than your desktop size, BioniX will make them fit without cutting)
* smart tile (if some of your pictures are tiny, BioniX will tile them).

The images from the playlist are displayed by the wallpaper changer randomly / shuffle or continuously. While running, the wallpaper manager skips invalid image files (that don’t exist any more in your computer). On Windows 98, it switches automatically between Active Desktop and normal desktop.
