How to add H1 to home page

[Godfather]

We are using a custom image header at our site:

http://noteinvestor.com/

We have a site title that is filled in on the Title area under General Settings. This same site title is also filled in on the "All in one SEO plugin". It is is accurately showing the home title above the browser bar when viewing the site.

However, this title is NOT showing as the H1 when you "view page source".

I think it is because we are using a custom image header instead of just words which would usually show up as the H1 on the home page on this theme.

Any suggestions on how to add H1 to the home page?

We are going to upgrade this to a Genesis theme but for now I'd like to fix this.

Thanks!
