A site that I use frequently is iStockphoto to find illustrations and photos for both client jobs and presentations (they are also a sponsor of my blog, but I am a paying customer too).
They just released a very cool plug-in that let's you search for images right within some of the key Adobe apps. It currently works in Photoshop, Illustrator and InDesign (I'm hoping for some of the video apps in near future).
The official blurb
