American Greetings has tons of nice wallpapers for you to put on your desktop. The selection they have is pretty darn good. They've broken their desktop images into different categories, like Inspirational, Graphic Patterns or Seasonal and they never have adware or spyware in their files. Another nice feature with their free wallpapers, and one that I love, is that you can download in a number of sizes from 800 x 600 to 1600 x 1200. I cannot stand it when you find a wallpaper and it's only available in 800 x 600. Who uses that sceen size anymore anyway?!
