Suga,
The NBL need to go into the room of mirrors and have a good look at themselves.
If the NBL can only take photos from Getty then they need to consider sacking them. If Getty can't get to games at all stadiums, or establish a reliable network of photographers to feed them photos, then they are not delivering what many would consider to be an acceptable service.
Do the NBL actually pay money for Getty?
IMO, each game is covered by the home team's official photographers anyhow. Why not ask them to submit a selection of photos from the game to the NBL (ie yourself) who can then display the required pictures.
That way, we don't get those maligned photos from away games of photos from homes games.
