I just released a new version of the Yanapax Viewer. Version 3.1 now supports Social Network Sharing. A new “Share this Comic Book” button (as displayed on the left) is located on the navigation bar an allows readers to share the Comic Book on all major Social Networks, including: Facebook, Google+, Twitter, LinkedIn, StumbleUpon, Reddit, Delicious, Digg and My Space.
I implemented this new feature using http://share.lockerz.com/ API.
I hope you find this new feature useful since it was one of the most requested features. Enjoy!
