Paul, When I first joined the site a few months ago there were only a few pictures posted for critique. Now it seems that people (mostly from another site that is closing down and I stopped using the this very reason) are posting as many as ten or more at a time. Some are worthy of a critique, but most seem to be snapshots which should not be there. To make a decent critique is time consuming and it is impossible to do it for everyone. Some way of limiting pictures for critique is required and your suggestion of credits for comments seems a good possibility as long as it can be automated.

Just my 2p worth. Rex
