Chris,
"Can you scan art into Photoshop & turn it into a vectorized picture?"
Yes, you can. I do that frequently. I use the Segmation plug-in for Photoshop <
http://www.xaostools.com/products/segmain.html> from Xaos Tools. Segmation is explained in this comprehensive review of Segmation 1.0 <
http://tiemdesign.com/reviews/archive/segmation/default.htm>. Here is another review of Xaos Tool’s Segmation <

Because Adobe has for some reason not maintained compatibility with older plug-ins, Segmation may not work with current versions of Photoshop. I keep my Photoshop 5 installed on my system to continue to enjoy my older Photoshop plug-ins. I actually haven’t tried to use Segmation with my Photoshop 7, but somehow I doubt that it would work, and unfortunately Xaos Tools hasn’t developed a later version of Segmation for current Photoshop versions. I personally think that Adobe should make older versions of Photoshop available free-of-charge to current owners of Photoshop to deal with problems of this sort. Of course, backward compatibility would be good, too.
