I think this is well in line with an idea I have had for some time.
Probably we'll soon be in the situation to have too many snippets to be 
conveniently used so we should somehow have documentation.
I'm thinking about a script that creates Markdown files from the 
snippets themselves, respectively their headers. Github will then 
display them as HTML pages automatically.

Adding images to that documentation is surely a good idea.
Could you please add an issue to the repository's tracker? This will 
reduce the risk of the idea being lost.
