Changing the Header/Footer Image in a Global Template

Before adding your own image to a global responsive template header or footer, you must upload the image to the image library. Click here for a guide on uploading images to the image library.

Go to the image library and find the header or footer image you would like to use.  
Click the Full Size link above the image preview.
A new tab will open and the full size image will be displayed. Copy the URL.
Navigate to the templates maintenance page and create a new template.
Click the Templates button at the bottom of the editor and select a gobal template.
Right-click the header or footer image that you want to replace and click Properties in the menu that appears.
Delete the URL in the Choose Image field and paste your image URL.
Click OK at the bottom of the properties window.
You image will now appear instead of the global template image. Click Save to finalize your work.
