Find technical information, pictures, logs and histories of passenger and cargo ships.
There is no single comprehensive index of ships' pictures. However, there are a number of extensive indexes and collections, both online and in print, that are well worth checking.
You should bear in mind that unless a ship in operation before 1875 'had a very lengthy life (which was unusual), it is most unlikely that any photograph exists [...] Sketches, pen and ink drawings - even an occasional oil painting - do come to light, particularly of popular or fast ships' (source). The more modern the ship is, the more likely it is that an image will be available.
If you find a result in one of the picture indexes, remember that several ships may have had the same name. You should try to confirm that you've found an illustration of the correct ship, by cross-referencing with the information that you have found in other ship identification sources.
