SharePoint News Rollup Image options?

Hi Brent Ellis - Yes it looks terrible. Today (~1.5 years since your post)  I wanted to create a news post about about a new MS Teams channel. The News Post describes the purpose of the channel and it includes a screen shot of the top of the channel with the tabs highlighted.  The home page of the site contains the News web part and since I chose no header image it used the screen shot, but it just a small portion of the screen shot and it is zoomed in so the thumbnail is pixelated and terrible looking.  If I chose to use a custom image as the header of the news, I could set the thumbnail image, but the header image is a terrible waste of screen real estate.  I think I will go that way and cross my fingers that someone at MSFT is working on this.
