1. There are lots of places to search for photos on the web. The biggest issue is getting to use those images. For example, Flickr doesn't act as matchmaker - you will need to get permission from the photographer to get the photo. Which is certainly right, but you should be able to get royalty-free pictures immediately, too. We are going to try Stock Exchange.

2.  Create an account, and search for pictures. Note that there are paid-for items on the bottom of the page - made by pros. Download the pictures/photos related to your subject matter/topic.

3. Save at least 10 to use at a later time.
