One of the most useful tools you'll find for capturing something on your screen is SnagIt. If you can display it on your screen, SnagIt can turn it into any file format you want (jpg, tiff, bmp, png, etc). This is especially useful for something like WordArt in any Microsoft product. Simply create the WordArt you want and use SnagIt to turn it into a transparent PNG that allows you to set the background to a transparent color. The company has a free trial on their site so it doesn't cost you anything to try it. I use it all the time to create graphics for the Workshops I teach.
