Implementing avatars timeline

From time to time I like updating my avatar, but this has the side effect of changing it also on old messages that I wrote with another face.

Recently I was able to recover an old repository containing the sources for this site for the period 2007-2012.
Reading my 10 years old articles was entertaining (for me) but having my grown up face next to a 13 year old post felt so strange.

So I decided to implement an avatar timeline. At least here on my website, every post will always have the face that I had at the time of writing (except on mobile, I don't display my avatar on mobile).

I don't expect anyone to be interested in those old posts, also many of them are written in italian.
In any case, they are all tagged with #abisso.org archaeology
