Why won't my signature work?

[Enigma]

I've tried to change my signature, but every time I change it the image turns out broken.

I've even used the "[img]" tag things correctly, I'm pretty sure.

Any idea what the problem is?

Copy and paste exactly what you're trying to put in

Its not a direct image link, open the image in a new tab by itself.
