Post Format: Gallery (Tiled)
This is a test for Jetpack's Tiled Gallery. Install Jetpack to test. This is some text after the Tiled Gallery just to make sure that everything spaces nicely.
Post Format: Video (VideoPress)
VideoPress, especially as a video post format, usually provides some unique styling issues. You will need to install Jetpack or Slim Jetpack plugin to turn the shortcode into a viewable video.
