Web Page Guide This can help you pick the right graphics for your homepage. It has many to choose from and is very helpful.
Adler's Gallery This site is pretty highbrow, but also very pretty, has lots of buttons, bars, tiles, and sets to use in return for a link on your web page.  You can also purchase an exclusive license for the sets.
The WebVoodoo Homepage This is a campier collection of buttons, bars, sets, etc. WebVoodoo also offers design services.
Seal Beach Mantras This well designed site has lots of really neat icons. The icons are in zip files that can be downloaded.
Ulead Systems Innovative Multimedia Solutions This is a site with free trials of some great graphics programs. They are really user friendly and fun to use. 
Macromedia Another company with some AWESOME trial versions of programs. Most of them aren't too pricey but some are very much so. They also have a very good graphics oriented webpage displaying some of the latest graphics.
VL WWW: Images and Icons Good site with lots of links to sources for icons and images.
The Clipart Connection This site houses a large collection of free clip art.  The images are sorted into categories to simplify the process of finding what you need. The site is primarily geared toward the construction of webpages.
http://www.geocities.com/Paris/8319 This site features bizarre, old-fashioned clip art.  The low quantity is made up for by very high quality.
http://www.clip-art.com This site has a large collection of free clip art and animated gifs. The images are categorized to help you find what you're looking for. The art isn't the kind of low-density graphics contained in most clip art databases. A lot of it is photographic and detailed.
