Don't restrict yourself to the whims of those screeners - consider a free Fotopic site,or Flicker / Photobucket as well,where you can upload pics that may not be accepted by A.net etc.A lot of people looking to buy pics start with a Google search of the aircraft reg / type they are interested in - and then onto whatever database the particular pic is hosted on.
Photos don't have to be A.net / JP standard in order for others to want to use / purchase them.
