OwnDrop.com header issue HELP??

I created a Header.jpg for my site OwnDrop.com, when I uploaded the header to the site, the Site Title and Tagline was hovering over it. I fixed this issue by removing the Text from the Title and Tagline in Wordpress. The issue that I still have is there is a Q type logo that is still there hovering over my header, this logo came with the theme! I have looked around in the theme editor, but I couldn't figure it out. Can anybody point me in the right direction?

I figured out that it's an image called "header-icon.gif"

What is the best way to make it so this image doesn't show? Do I want to edit something in Theme Editor? Do I want to just delete the image, no sure if this is the best option?

Let me know what you think?

Issue Solved, please close!

Thank You
