comprehensive online dictionary with pics?

[Marnie E. Arkenberg]

I am looking for a comprehensive online dictionary and/or encyclopedia with
pictures included in the definitions.  I have found several children's
dictionaries, but nothing on par with, for example, the unabridged Oxford
English dictionary.  Is anyone aware of either a site or software that is
comprehensive in terms of pictures (I am looking for pictures for both concrete
and abstract words)?  Furthermore, could anyone steer me toward word learning
research incorporating this kind of technology? Thanks to anyone who can help!
