A sample markdown post
This blog post uses Markdown. It supports standard markdown syntax. In addition, there are a handful of helper codes for videos (youtube and vimeo) and for working with images with lightbox.
You can use the lightbox by itself or lightboxmax to have the image at max width.
Below this section is a gallery. You can set 1, 2, or 3 columns across and it sizes everything for you and clicking the images displays them via lightbox.
