Gallery Not Showing Correctly

Hello,

I’ve noticed that unless galleries are posted as a thumbnail grid it appears very small. This mean the tiled mosaic, square tiles and other gallery styles as allowed by Jetpack can’t really be used. Is there a way to fix this issue?

Here’s a page on my blog whose gallery has been set to tiled mosaic as an example – http://esotericgentleman.com/lehnah/gallery/
