If you don't have a cover image, your game submission in a game jam will appear as a blank image with the text "no image :(", even if you have screenshots or other images in the screenshot section.
Oh, that's a good thing to note! I should double check what happens on your profile page and in the itch browse results if you don't have a cover image as well.
I'll do some testing and add a section for No Cover Image.
