Marat Nepomnyashy

Setup image galleries in a jiffy via shortcodes specifying image slugs, and 
 have the images load in a jiffy by downloading only the minimum size image 
 necessary for the client viewport size. Images are rendered as large as 
 possible within the viewport when expanded.
No locked premium features, and tested to work on iOS devices.
