add firefox button to site

I want to add the Firefox button (amongst others) to my front page of my site… the code I have is this:
<a href="https://www.getfirefox.net"><img border="0" src="https://www.getfirefox.net/buttons/110x32_rediscover_button.gif"/></a>

Can anyone assist in helping me by explaining how I would do this please?

It can sit anywhere on the sides of the page… my theme is 2011.
