Yes, but why bother with the specific ones at all? I don't think they are
really needed, as you can have a description "A picture of Earth" indicating
what sort of animal is at the other end of a link.

I don't think setting up yet another typing system is a good idea;
that is an issue for the URI (as in gopher URLs) and the negotiation in the
transfer protocol (eg HTTP's Accept: field). Where do you draw the line: 
CVUrl, ASCIIUrl, WordPerfectUrl...?
