Who says you shouldn't ship on a Friday? If you checkout gist.github.com, you can now easily include images and videos in your markdown files. Paste the image in or browse your file system to attach. Let us know what you think.
@github Did know but except if I missed a thing, I also do know I can't create directly a gist from images or videos using command line with github.com/defunkt/gist (need to create empty gist, clone it, add images/videos, commit & push...)
