Instead of using a normal email address, Bitpic uses Paymail address.
Instead of storing the imagess and the image database on a proprietary server, it stores it on the Bitcoin blockchain.

Bitpic is open and distributed. Anyone can run a bitpic node. https://github.com/interplanaria/gridbitpic
The images are 100% stored on the blockchain, signed by Paymail user identity public key. Images signed with invalid signature are not indexed.
