Yesterday evening I had some fun sitting up a static photo gallery on GitHub, using Jekyll and this very nice template.
Here is the link to my initial gallery (just few images for the moment, more to come soon!): http://aferrero2707.github.io/photorama/
All images use external links to google photos, but I believe that other storage solutions could be used as well (including storing the files directly on github).
From my initial tests, this looks like a very easy way to set up a web photo gallery, and the result is in my opinion really nice and professionally-looking.
What do you think?
