XF 1.5 IMG tag in a Phrase

Hey there,

I have just tried adding <img src="someimage.png"> to the forum phrase, but I am simply getting the tag displayed.

I thought the phrases accepted normal HTML?

Any thoughts?Screen Shot 2017-05-31 at 12.30.34 PM.png
So the default Xenforo FORUMS navtab doesn't support it?

If not, would you suggest CSS as being the next best option?

To be clear, the html is showing in the inspector, but is black font. I assume this means it is added as a text, during DOM load?
