How do I fill my pockets with Pocket tokens?

Just discovered Pockets on Steemit after I received a few in my comments. (Shows how much attention I pay)

This has got me wondering what else is possible with a sub-chain like this that allows you to create a new currency. Mind Blown!

I'm not a developer but I think I've got a grasp of how it works... A digital asset is transmitted inside the main blockchain and effectively tracked by the sub-chain software. This is a clever idea that can further monetize Steemit with sub-currencies.

Imagine if every action on Steemit had a token reward attached to it that could be exchanged for SBD. Every post, Every Comment, every search, every profile update even every time you visited the site. I think these would need to be implemented by Steemit rather than externally but even so, the potential is interesting. It just goes to show that Steemit could continue to evolve with limitless possibilities.

Since learning about these sub-chains, I was thinking, wouldn't it be great if every uploaded image was monetized by the amount of token rewards it received. I wonder if this is possible without having to manually submit every image?
