http://imgur.com/AM11LCz Working on my website for my wedding. Using it as an opportunity to teach myself Django, so that I can make mistakes here before I start using it for a work project. Right now, I'm working on adding the ability to RSVP for events. It's been really great to learn how to use Docker, Redis, Postgres, etc. to make this come together. Overkill likely, but still fun. :-)
In my case, privacy was the main reason to build the site: I did not want to share pictures of random guests (in more or less drunken state even) on the web. So we selected only images of ourselves and put all the others behind a login, accessible via a private mail with a token. Guests loved the fact they could download all the photo's too, there. :)
