Header Logo – Image instead of Text

I am designing a website using a child theme of wp-forge.

My website

I want to have the header divided into two images; one the main logo ‘SCoVE’ displayed on the left side; the other the two logos currently displayed on the right. I want them to be separate, so that they can link to different web addresses.

Can someone show me how I can go about doing this? I have played with editing the header.php to make ‘header-info’ display an image instead of text, but I don’t know how to specify the image to display: I’m lost.

Thanks
