Drawille is amazing. I built an image viewer for the terminal with it, very rudimentary, sort of 'cat' but for images https://www.npmjs.com/package/tty-view
Wow, I googled for a project that could do this and found Drawille literally last night.
I was looking for a way to quickly display graphics right in the terminal, cross platform and with default settings. I wanted to build a simple python library that would allow you to graph 2D plots without opening excel or using a graphing calculator. The best alternative I could think of was using the PIL to draw and image and quickly .show()ing it
Pretty cool. And if people are wondering, yes, screenreading software can output this to a braille display. However, mainstream displays only have one line of braille making 2d images somewhat more difficult to understand.
A usual method for forums and such is to embed an image with an src hosted on your domain, then analyzing the logs. I used to do this to mark forums as read in a browser game I played, as a player-linked ID was in the URL (sent in the referer)
Github solves this particular method by downloading the src and mapping it to camo.githubusercontent.com, so maybe OP didn’t realise that, or GitHub shows the stats somewhere.
