--- Some things to ponder about Google Images ---
You've probably used Google Image Search before. Like its big brother, Google Search, GIS is quick and easy to use, and more often than not you can find the image you're looking for without too much effort. However, because it searches for image names and contextual words on the basis of popularity, results tend to be uneven. Additionally, images from websites indexed by Google are often small, poorly scanned, have been altered in some way, or are in violation of copyright, making them inappropriate for use.
