How to get clickable Pictures in the Z8Games Forum...

Hi out there,
I wanna know, how to do Pictures as link in the Z8Game-Forums.

I know HTML isnt allowed here, but it should look like this:

(In HTML its like that)

<a href="URL"><img src="image-URL" alt="...">
This would do a picture which leads to a webiste.

Could someone tell me, how to do it in the Forums?
Maybe a MOD

Ty and Greetz.
