Only FT shows what type of organization is downloading particular photo. Are there any restrictions for buyers on usage of RF photos?

melastmohican--  Quite often you can find out how your work is being used just by sufing the net under your name, tag or name of the picture.  I've found plenty of my stuff out there. I just found one last night.  Some Maine tourism agency is currently using one of my pix on their title page. Give it a shot, see what turns up.
      This kind of tags onto one of your other threads.  Nature/landscape does sell....   it just doesn't sell well.  Again, try pimping your own work. Shoot out some emails, snail mails and make some phone calls.
     As far as restrictions,  while most agencies are pretty much the same, there are minor differences.  As advised, you need to fine tooth comb the agreements you made with each site.  =tom
