images are not clickable in responsive mode

I have this problem on my S3 and on my PC if only one column is visible in responsive mode. Then when I click on an image, the bootstrap modal window is not visible.

My suggestion is to use Featherlight.js. With this plugin, all windows are shown correctly.
