How do I put an image in my signature?

I've seen other people do it in theirs, and I know there's a code in order to insert images in other places (which works in those places), but when I put that code in the signature, it causes my signature to be completely invisible and removed, as if I never had a signature. Am I doing something wrong?

You don't. Not sure where you're seeing images in signatures, but that feature is disabled on these forums.

Do you mean titles? The images there are "badges". Basically stuff you can put under your title.

I don't think we can do that, or at least to my knowledge. Can you please give us an example of what you were talking about? If so, that would help, thanks.
