I have tried to use the tiled gallery with Jetpack, but thumbnails do not seem to appear. The links to the images are there and can be displayed in the carousel, however the actual gallery is missing.
I've tried deactivating all plugins except for Jetpack, and the issue persists with the default themes twenty ten as well. Photon is disabled. Any ideas how to get the thumbnails to show?
An example can be found here http://henrypatton.org/tiled-gallery
Thanks for your help!
