I like http://www.fishbase.org but it is easier to use if you know the common name of the fish you saw or at least what kind of fish it was. Then you can do a search and look at the pics for the results. I don't know any that are less advanced/user-freindly. If you want a field guide with good pictures I use the Audubon guide but it doesn't include everything such as the gobyish thing I saw last weekend. Come diving with Neil and I, we're adapting hand signals for different kinds of fish
