I've got an image, I just want it to be above all the information.
You'll have to set it as a background image, then move your column down so that the image is visible. Copy and paste this code into a Blank section, or the Profile section:
<style> body, html {background-image: url(URL OF HEADER IMAGE HERE); background-position: center 35px; background-repeat: no-repeat;} {position: relative; top: XXXpx;} </style>
You'll have to put the URL of your image inside the parentheses, and change the XXX in the part to a number. Depending on how large your header is, you'll have to adjust that number until the whole image is visible. A larger number will move the column farther down the page.
