How do I get a banner?

[Vivat Imperatoris]

Some users seem to have banners in their signature. How can I add a banner to my sig as well?

You need a title thing for a banner, if you mean a signature image (not a profile banner) though grab a link and add it in your signature editor.

Thank you very much!

For some reason I keep getting an error that " something went wrong". Is there any constraint?
