“I know that I don’t switch wallpapers all that often but I know quite a few users who have purchased the wallpaper megaplex application from S4BB. The new catalog has over SIX AND A HALF MILLION wallpapers. I think that should cover just about every niche requirement.  With an average of 15Kb per wallpaper (as far as I know) that can be over 100 Gigabytes of wallpapers to choose from.”  Check out the Wallpaper Megaplex.
