I am using the Pinboard theme and I recently imported my WordPress.com posts to my WordPress.org site, which was a pain in the ass in and of itself, definitely NOT a smooth transfer.
Anyway, I have installed the latest version of Jetpack, activated and configured the Tiled Galleries so the options show up, but they are not working for me. I've tried several times (read 20 times or more,) but the posts still display small thumbnails.
How it looks on my wordpress.com site: http://thestarlinglife.wordpress.com/2013/01/01/goodbye-2012-hello-2013/
How it looks on my wordpress.org site after Jetpack install, activation and configure of all options: http://www.thestarlinglife.com/2013/01/01/goodbye-2012-hello-2013/
I'd love to know what I'm doing wrong because I want to be able to use mosaic, square and circle galleries on my self hosted site.
