It surprises me when these small boutique so called stock agencies charge money to join.....The big ones, Getty Images (USA), AAp Image (AUS), AP (USA), SMP Images (AUS), Reuters (CAN), Corbis (EU) dont charge a cent for you to be deemed a contributer. Having worked for and in close relationship with these big companies i know this for a fact.
The other problem is now that flicker and several other happy snapper contributing stock agencies have been bought out by the big boys, they now sell their images for a low as .99 cents.....does this leave any hope for the happy snapper / amatuer photographer sending pics to be considered for sale through stock companies.

?
I personally believe that you shouldnt have to pay for contributing to stock agencies...... All of the big major agencies have their clients on a subscription base and do in fact make money out of every sale no matter what - i know our newspaper network has subscriptions with all the above listed agencies. So why should you have to pay them to increase their business with your pics...

The other big question looms - what do these agencies that you pay to join actually do to :-
1. Promote and market your pics to clients.
2. Where do they actually find their clients from, considering most major publications / newspapers / electronic media org's go through the big agencies listed above , especially considering how easy it for them to access the content they require, and that they know they are going to only have top shelf quality images to choose from.
3. and with so many people submitting pics , what do they do to help you grow your pics for which clients might actually seek to obtain for use.
