Adding a link to custom header on Studio theme

Hi,

I have recently purchased Studio and all is currently going well with the build.

What I want to do is add the custom header option below the theme menu and add a link to it. What I'm looking to do is sell the space to an advertiser.

I therefore need to somehow add a link to the image, could someone please describe how best to achieve this.

Thanks
