Follow Me button - beginner


I am fairly new to this, I know a bit of html and I’ve got GoLive.
I’ve made a basic website and want to put a Follow Twitter button on it but I just cannot get it to work with an image. I’ve downloaded the follow me code and placed it in the head but twitter address just sits visibly above the image button.
Does anyone have a very simple answer for me please?

Thank you,
