As with all good graphics programs, Painter is capable of importing images from clipart packages.  

Clipart comes in two forms, vector and raster (bitmap). For a comparison of the two, go to Vector vs. Rastor. Bitmap art is very straightforward for Painter because Painter is a bitmap editing program. All it takes to import a bitmap image into Painter is to open it.

Vector clipart is a little trickier because it's not composed of dots, but is a mathematically defined object. Bringing vector clipart into Painter requires converting it to Adobe Illustrator format because that is all that Painter 5 supports. Corel Gallery Magic is the only mainstream clipart package that has a conversion program that can do this. For more info on this program go to the Import page. [Note: Painter 6 appears to be much more finicky when it comes to importing vector clipart and is prone to crashing when importing Adobe Illustrator files. Corel Gallery Magic is no longer published by Corel and it does not appear that their new clipart packages have as robust an export feature. Corel Gallery 380,000 does not export to Illustrator. I do not know if any of Corel's other packages do any better a job of exporting clipart. All in all, it probably isn't worth the trouble trying to import vector art into Painter. Hopefully, Corel will provide more import filters in an upgrade and will do a better job of stabilizing Painter's ability to import vector art. Now that Corel PhotoPaint and Adobe Photoshop work with vector art, Painter no longer is unique in having this feature, but it was there years before competitors copied them.]

Corel Gallery Magic isn't the most intuitive program in the world, so a tutorial is provided.
