Photo Thumbnails not responsive.

We've installed JUX Social Gallery and created a module with two tabs (FaceBook and Instagram), which is placed only on the home page into a module position. The website is www.farwestfungi.com . It's a current Joomla site using Yootheme's Eat theme (Warp 7 framework). The JUX Social Gallery image thumbnails are not reducing or centering or stacking when viewed vertically on smartphone devices. Is there a way to adjust the minimum size (or the device responsive sizes) of the thumbnails so at least two images will center properly on a vertically positioned smartphone? Also when more thumbnails are configured (four example four or five) the thumbnails do not stack into intelligent columns and rows as many other galleries do. Can you advise us as to a strategy to display a minimum of four images per tab and then have the images within the tab respond by reduction or stacking to accommodate a vertical smartphone view?
