Hundreds of photographers are using the web to license usage of their
photos directly instead of through the few surviving agencies.
There's a whole discussion list on yahoo devoted to stock photography
from which you could learn a lot before you reinvent a wheel already
in use by hundreds of people.
There's a professional society for stock photography artists called
the Stock Artists' Alliance which is very active in promoting
education and the work of its members.
Check them out.
