What is the best way to include graphics in a question or an answer on MO?
I searched the help but could not find instructions about how to post graphics. I also looked at a couple of Joseph O'Rourke's posts but I was too stupid to be able to figure out how he did it.
Also I am wondering if some methods are more "universal" than others. Occasionally some MO answer will contain a graphic that I cannot see on my work computer, probably because of various filters that have been installed for security (blocking Java and Flash for example, as well as content from "untrusted" websites).
