Need help putting Firefox promotional buttons in sig

[xamenus]

Well, as the title says, I can't get the Firefox promotional buttons to show up in my sig; I think the HTML code provided there is faulty (unfortunately I'm not fluent in HTML). It would be nice also if I could get the image to show at the right of my specs, not below it. If anyone could help I'd appreciate it.

Here's my current sig code, maybe someone could add the Firefox HTML code to it :

Here is the code, the name of the image and the custom text are not included.

Thank you, I really appreciate your help. I'll play around with it some more to see if I can get it to show at the right of my specs.

EDIT: Or maybe it will be fine as it is.
