needs update for TwentyFifteen

Eazyest Gallery works and looks wonderfully on theme TwentyFourteen and WordPress 4.1.
But its gallery display shows gross vertical spacing problems in TwentyFifteen and some other of the most recent responsive design themes.
Unfortunately I could not work around the problem by debugging in HTML or CSS or PHP; there seems to be some kind of jQuery command that attaches a large vertical height to each thumbnail cell, making the rows widely spaced and mostly empty. Shucks. I really like this plug-in for how easily it lets me compose a gallery of 135 images.
