When creating and publishing new events using the Steam Event tools, you will be required to supply a set of graphical assets for your event. These assets are used on the event page, as well as various places on Steam, including your store page, Community Hub, and in the Steam Library. The exact location of all communication depends on the type of event, user preferences, and the context in which the event is displayed.
Cover Image RequiredSize:
800px wide x 450px tallDesign:
This image should primarily contain the artwork and branding for your event. Steam will always automatically include your game's name and icon next to the cover image, so it isn't critical to include your game branding in the cover image (but you may still choose to do so).Usage:
It will appear on your store page in recent announcements, in lists of events and announcements, and on your game's library detail page. It's used to link to your event/announcement and may be displayed alongside content from multiple games, so the image should be clear and recognizable.
