LINKS - CLIP ART
Many graphics sites offer clip-art such as icons, buttons, lines/dividers, gizmos, etc. They may help to 'brighten' a site somewhat but care should be taken not to overdo it and overwhelm your visitors. Note that many of the sites listed here may well be worth checking out for other types of graphics as well.
Animated Clip Art
Wandering across a wonderful webpage or finding exactly what you are looking for becomes a disappointment when you are confronted with a ton of irritating animations on the page. They take longer to load and while they may look cool and cute the first time you see them, you'll do your visitors a favour if you restrain the urge to use lots.
The Animation Factory has 12,000 original animations for use on web pages and e-mail. All graphics have been 3D rendered and are completely original.
The Animation Library has over 13,000 animations online for you to use on your website, plus articles, reviews, tutorials and everything else related to animated graphics.

They also have PSP tutorials which I have not visited as yet ... if you find it worthy of a note here, please let me know.
