Online Stock Photography:

There are two kinds of online photography available: royalty-free and rights-managed. When you purchase a royalty-free image, you can use it anytime you want. Rights-managed photos are one-time use, and varies in price (usually more expensive). These are the ones I used the most, but just type in your browser "stock photography" and other websites will pop up.www.dreamstime.com (varies from $1-$10, depending on size)
www.123rf.com (subscription or $2 hirez)
www.fotolia.com ($2 or $3, depending on size)
www.sxc.hu (Low cost too. The first one is always free...)
