[Theme: SmartOne 1.0.2] Header image link

I want to make the header image on my site a clickable link so that viewers of the various pages have easy and intuitive access to the home page. I’ve Googled for solutions for a few hours, but so far everything is outdated or unworkable with my theme.

Is there a certain plugin or line of code that can do this? Any relevant advice anyone could give me would be appreciated. I can post the code to my header.php if necessary. Thank you in advance.
