Falling Under the Spell of "The Clip Art"

I wish there was a better term for the royalty art one can find under the "Clip art" heading.  To me it seems to be a disservice, as prior to my recent finds, when I thought of clip art, I thought of really simple / lousy thumbnail sized pieces of art.  Thank God I'm proving myself wrong the last few days.

My latest find can also be found on RPGNow.  Eastern Raider Games has a Portrait Package of 36 images listed at $4.49 for the set.  The price drops to $1.99 for the set once I put it in my cart.  That's about 6 cents an image.  Heck, if I only like one, it's still less then 2 bucks for it's usage.

I'm very much liking the idea of using licensed art for inspiration ;)

Here's the very liberal license conditions:

The package also contains a license.txt file thus giving the buyer the right to modify the images
(crop, blend, rehue, resaturate etc.). Anyone who owns this license may use the artworks in
any way (s)he wants, in any number of commercial products without the need to pay
anything, not a cent of royalty. The only exception: the artwork (even derivative ones) cannot be
sold in themselves, they have to participate a specific project.

The package contains mostly portraits and mostly fantasy/SF/Horor themed ones.
Might be useful for Web sites, MMORPGS, forum avatars, DMs, players can impersonate their character/world
