Dukky Design 2.0 allows a background image as well one main cover image.
Main Cover Image
This image is the large image at the top of your promotion site and will double as the image shared via social media shares. Image size - 800 x 500 pixels (png or jpg).
The background image isn't an exact size since it varies based on which device a user is coming in from. The file should be a jpg or png format. We recommend subtle repeating patterns for the background.
