To change or remove the background picture on your page, you must first be logged into your account and in Studio view.
On the lower right corner of the default background image there is a camera icon with a '+'. Click on the icon and a prompt box will appear. Here you will have the option of either choosing from our sample images or upload your own image file. To choose a sample image, select the image you want and click 'Save'. To upload your own image, either drop the image file into the box or click on the box to find your file. Once you have found the file, click upload and your image will now be loaded as your background picture.
