As an administrator, you can define a default image for all news. Should a user not include a custom teaser for their news, the default image will be used.
Upload a Default Image
Images are a great way to attract attention. To avoid news items without an image, you can define a default image in the admin area. This image will be used for news feeds (Corporate News Feed and Personal News Feed macros) as well as for the Cover Stories macro or tiles in the News Center, as long as there is no News Teaser macro within the content of your blog post that defines anything else.
