Allow Vendors to Set a Grid Image
Note: This article requires the Multiple Post Thumbnails plugin to be activated first.
Allowing vendors (using Easy Digital Downloads - Frontend Submissions) to upload their own grid image is very easy. Once the Multiple Post Thumbnails plugin is activated simply navigate to "EDD FES > Submission Form". Find an existing "File Upload" field (or add a new one), and check " Use this image as the grid thumbnail."
