Just thought I'd repost this as it's own thread....
Like everyone else my siggy reverted and updating it a million times didn't work. I searched and came across this solution and it works! Instead of going into Edit Avatar & Sig like before, look for the 4 icons she describes below. You should see them in the top right of the page under "Community" if you are on a computer (this won't work mobile bumping).
These directions were posted on May '13. They worked for me, so hopefully you all will find success, as well.
In the upper right hand corner are four icons (a globe, something else, a star and a person)... click the person.
Click preferences.
Under your avatar, there is a link that says "signature settings".
BEFORE YOU START TYPING STUFF IN THE BOX: click the < > icon (show source).
Then insert your html code.
Then click the show source button again.
You should be able to see the pictures... not code.
It worked for me, hopefully you guys can get it to work for you as well.
