Make sure that the licensing on the image gives you permission to add them. An easy way to make sure if that is to choose Creative Commons-licensed images. You can find great re-usable images on Wikimedia Commons, at http://flickr.com/creativecommons, or by using the advanced search within Google Image Search, just to name a few options.
