Adding extra header image

Hi Firstly this question is for the Catch Everest Theme as I couldn't seem to post on there for some reason? Anyhow I have a logo in the top left hand corner or the home page. I was just wondering if there was anyway of adding extra images to the header? For example I would like another one in the top right hand corner. Also not sure how these themems work, is certain code hidden? The reason I ask is because when I inspect the element on the webpage I cannot find the same code on the editor. Thanks
