^^^^^ I agree with Sgt_Kickaxe, they may rank somewhere but one will be better than all the others.
Is that bad, what should i have for them?
Your best hope is that the "beach at Sunset" image which ranks the highest is your best one thus dragging in visitors.
With 2 million images you do have a slight problem though but how many galleries will you have, 70,000?
If so and if they're all good images I'm guessing that Google actually may like them since you will have done a huge amount of their work rather than them having to work out precisely what is there.
