Colorbars are used on your site or on your info page (in LiveJournal or similar places). All you have to do is paste the code found on the page that pops up when clicking on the bar or text. Find the bar you want and take the code under it, by highlighting and copying. Then insert it on our own site. Pasting the code means that you don't have to worry about saving the bar anywhere, or linking to the right page or anything. It should all happen automatically. ^^
