I'm experiencing a rather strange issue with modern team news. I have this issue on two different O365 tenants. When a team site has a header image - the news thumbnail will render the site header image, not an image from the news post. This is the news web part - the news item thumbnail is the same image as the site header: Even though the news item looks like this:

We cannot specify the thumbnail image, it is decided for us by Sharepoint - this is a real problem for content managers !!i.e. Sharepoint will automatically set the thumbnail image based upon the 'first' custom image it finds in the news article. So if I use a custom header image it will pick that for the thumbnail too.This is a real problem because quite often we need to select different images because of the difference in aspect ratio. i.e. What works at thumbnail ratio doesn't work at super-wide ratio in the header. SEE example attached - [Thumbnail and header]- it just doesn't work !! We need to have the ability to set a specific thumbnail image 'independently' of the images used in the new article page.

Toby Hallam - actually, if you click Page details, you'll see the option in the right pane to select a Thumbnail photo. That photo will appear in the News rollup.However, I cannot display the image in the CQWP.

what if you dont see the change image option?? is that a site setting? Melissa Liston

Thanks for the pointer Melissa Liston , however I dont see that option. 'Change Thumbnail' is missing from the the right hand panel. And in true Microsoft style, one problem leads to another,... Every time I open the 'Page Details' panel the whole page locks up and crashes.

Same thing. Can't change the thumbnail. Is it only for some releases?

I don't know if this is still relevant but, I figured out a work around.
You have to select the "image and title" layout. Once you've done that you can navigate to the page details and change the thumbnail. Then you return to the layout and choose the "plain" to just have a text title. It keeps the thumbnail but doesn't require you to have the image in the title!

  Yes, it may be related to early release settings for your org. https://support.office.com/en-us/article/view-edit-and-add-page-details-778018d3-8269-4fd2-a55d-8c0e5b72b938

Hi Edvard,

Could you please provide some more details on this one? Is the site you are seeing this on a classic team site or a modern team site? Do you see the same thumbnail generated for all the news on that site?

Thanks!

  Hi Alina,
  
  I think it's a classic team site (there is no O365 group created along with the team site)
  Yes, all news items get the same thumbnail
  If i temporarily remove the header image, post my news item, then reapply the header image. I get the desired result.
