iStock Photo: $2 to $4 per image

I read about iStockphoto.com in an article about globalization and crowdsourcing. These inexpensive photos look like they'd be great for desktop backgrounds (I use black and white images with limited white areas for my wallpaper so I can see icons) or presentations. Sure, you can find photos for free using Google, Flickr, etc -- but these are pretty nice quality. Might be worth a few dollars to save search time.
