PowerPoint presentations. Adding a few Christmas Clipart images or other holiday images could really spice up a PowerPoint during that time of year.
That is one reason why people often pay for a membership in a clipart site. They get to choose from a huge number of clipart designs for one small fee. It saves a lot of time, and if you have a bit of money that you could use to invest in a big time saver, then this would be a place to put it.
If you love wallpaper for screen savers you can find those on Cartoon Clip Art World as well. Most of the bear clip art is of the paws of a bear, flags made with bears, plus bear crossing signs, not just the entire image of a bear.
