Yes, I enjoy Webshots. I ended up shelling out the 20 bucks for a years worth of unlimited access when they started restricting downloads to 5 photos per day. Now I'll just get all the collections and put them on a cd and have them for years to come. I used to use Second Nature software for wallpaper and screensavers, but Webshots is more affordable.
