Replace Campaign Featured Image
You may want to change your campaign Featured Image at some point in time. Doing so is easy.
From your Campaign Dashboard select the campaign you'd like to edit.
Once the campaign is loaded on your screen, hover over the Featured Image and click the Edit Featured Image button that appears.
A new dialogue will open where you can choose to select a new Featured Image from images in your Media Gallery or upload a new image from your computer.
Once you've selected your new Featured Image select the Next button and your new Featured Image will populate on the Campaign view.
