Office 2003 have a strange Arrangement with clip Art, compared to Office 2000 where it was only 2 clicks away.
Forgot to mention this bit last night 
In Ms.Office 2003, View>>Taskpane, click on Insert>>ClipArt>>Organize Clips>>Office Collections>>click on the folder of your Choice to select a Clip Art, if that is not sufficientthe easiest way would be to click on "Clipart on Office Online", in the Task Pane in Word etc., then click on the Various Icons to collect the ones you like, which will be saved in the "Clip Art Organizer" automatically, and Open in the Word Task pane, for a quicker "find".
If you use Clip Art a lot, why not uninstall Office 2003 and install Office 2000, not much different are they,(except for the Clip Art, ) don't know if it is a good Idea to have both of them installed at the same time on your PC, or if you would be able to do that?
PS. In Office 2000 one had the chance to import Clipart from earlier Versions, but it seems 2003 does not !
Will put the Question in the Computer Help Index if one could work around this.
