Hearthstone functionality will definitely be improving very soon. The intention is to make deepbot able to pull win/loss information directly from the game client, rather than relying on manual input, which is prone to abuse and fudging. I was able to get a HS key for Experts today, so expect much more in terms of Hearthstone integration very soon. As for your request of having a picture link at the end of the description, I fairly certain that will be added in the next update or two.
Cheers!
