Hey, how can I get Discourse to do X?

My browser profile went kaput, and I had to rebuild these rules (after finally finding this post). For those that need slightly more fine-grained avatar whacking:

##.topic-meta-data > .reply-to-tab > img

##.title > img

##.reply-to > img

##.posters

##.avatar was a bit too broad, only because it makes it tricky to get to your user profile page. And once again, thanks to demagogue for showing that this was doable so easily in the first place.
