1. You don't have to print these out in color just because some of them are in color on the screen.
2. If you're going to print these out or look at them repeatedly, it'll save your time if you download them without opening them. Otherwise it'll take forever if you constantly have to toggle back and forth. For example, if you're on Netscape with a Mac, click on the link and hold it until a menubox opens up and then select "Save Link As...". The .gif file will download to your computer and you can open, view or print them at your leisure.
3. If the images look funny, check and see if if you're using a Microsoft product to view them (like Powerpoint, Word, Explorer, etc). I produced these with a non-Microsoft program (Canvas 5.0 by Deneba Systems) and sometimes they look blurry through a Microsoft product. Try a general picture or paint program that can open .gif files.
