You can change the site logo in the theme options panel at Global → Logo. You can enter a full URL to your logo image or upload a custom logo by clicking the Upload button. We recommend your logo be no larger than approx 200px(w) or 85px(h). Remember the navigation bar has to fit in-line with the logo, so there must be room for both.
Adjusting the logo position
In the Global → Logo section of theme options panel you will see Logo “top” position and Logo “left” position adjust these sizes to suit your logo.
Changing the logo link URL
You can change the page that your logo will link to, which may be useful if you have a landing page that you don’t want to be your site home page.
