You will need the Full Write Events permission, or to be an organizer of the event, to perform this action. The permission must reach at least one of the event's campuses, and the event's calendar must be one you are allowed to use. For a group's event, the group's admins can do this too.
A header image is one of the easiest ways to make an event stand out. The image appears at the top of the event detail page, on public listings, and on shareable links, so it helps the event share information at a glance.
From the left-hand navigation, select Events > Calendar (or Listing for the table view) and open the event that needs an image or an updated image.
On the right side of the event detail page, hover over the event's image area. A pencil icon appears over the image.
Click the pencil icon to open the image picker.
Choose where the image comes from:
URL - paste a direct link to an image hosted online.
Unsplash - search Unsplash's free stock library.
Library - pick from images already uploaded to your One Church Software account.
Upload - upload an image file from your computer.
Once the image is selected and uploaded, it replaces the existing image in the right-hand column of the event page.
Tip: The recommended image size is roughly 1600 × 500 pixels. Smaller or larger images are resized automatically, keeping the original aspect ratio.
For recurring events, the uploaded image applies to the series. To change the image on only one occurrence, use the Actions menu on that event date and choose to apply changes to only that instance.
