One of the best resources for pictures of viral pinkeye is WebMD. The U.S. Centers for Disease Control and Prevention also has a number of images of viral pinkeye on its website.
Pinkeye is referred to by medical professionals as conjunctivitis, since it involves inflammation of the membranes covering the eye that are known as conjunctiva. It is not always possible to diagnose the cause of pinkeye from visual inspection alone, so it is important for those with pinkeye to see a doctor for tests. Viral pinkeye usually resolves itself without additional treatment, but pinkeye from bacterial infections may require antibiotics.
