Well at wallsrx.com you can use the pill imprint codes, shape and color to find a pill and most of them have images for confirmation.
Pharmer.org has a large database of narcotic pill imprints with tons of images available.
You can also use the drug info section at eckerd.com, you can do a search for the drug(s) in question and get medication information plus another link to click with images.
