Preview image doesn't appear on chat

Hi,

Thumbnail image looks corrupted when I share my website link in Teams app. If I share another website link, they all works fine.. Why my website images looks like this? Do you have any idea?

I have seen this before and the problem is that Teams does not always show a thumbnail when adding a link in a conversation. It's really a question of the URL you are adding and how teams processes it

@Juan Carlos González Martín - There has to be more to this answer.   Do you happen to know, what is TEAMS looking at in the HTML Source of the page to populate the shared link thumbnail?

For example, Facebook looks for OG META Tags.   

Or is there some other criteria they are using to determine when to share an image or not?
