So out of desperation I just allowed all large image pages to be indexed with it's own Canonical URL and not the Gallery page. No images were indexed till then.
It's been 2 days and I already see more than 200 images been indexed in the google images.
Is this pretty lame from Google?
I'm happy yet sad!
