Excellent program, every option that one would need in a desktop wallpaper program.
Especially useful is the Auto Size change options whereby you can specify different tile or centre options depending on the resolution of the image selected.

Pretty sure this is the best free one you can get. A lot of cycling options, cycle once and quit, timed cycling, ratings, custom resizing, everything.

I have over 22,000 digital pictures that I have spent countless hundreds of hours editing in PhotoShop. In the past 8 years I have downloaded and tried dozens of wallpaper management programs. I discarded them all, staying with my simple old obsolete program that didn’t work well.
Last year I finally struck gold. Wallpaper Master is the most amazing wallpaper management program that I have ever seen. If this doesn’t do just about anything that you can imagine to display your photos, you must be crazier about digital imaging than I am. (That would be pretty crazy.)
I am seeing photos that I had missed for years, buried in old folders because other wallpaper programs couldn’t display them properly. It has been a joy to have this running and see ALL my pictures again.
This program is not dead like most shareware. It is being updated by the author with new features and capabilities. TRY IT!!!!!!!!!!!! This will be the last wallpaper program you spend time evaluating. It is a keeper.
