Stock photography is easy to find, but free stock photography takes a little digging. These are my favourite destinations for free (or almost free) stock photos.
Stock.xchng
Photocase
StockVault
Morguefile
PIX
ImageAfter
PhotoRack
Free Digital Photos
Dreamstime (Not free but very low cost)
iStockPhoto (Not free but very low cost)
etc. is ... simply quick links to good stuff, mostly of the geek variety; webdev, webdesign, css, firefox, movable type, but may be anything that catches my eye and deemed to be share-worthy.
