Graphics can make or break a website.
The judicious use of graphics enormously enhances the navigability of any site. I have a small library of files that have been picked up over the years. I can make no claims all of these are freeware or not copyrighted in some way, so you and I both assume any risk that may be associated in using them. Now that the legal stuff is out of the way, feel free to take a look at them. You will see a simple directory listing which lists both the files and folders on the site.
