Embedded link images not appearing as thumbnails in Notion databases

I'm making an attempt to grasp tips on how to make photographs inserted by way of embedded hyperlinks appropriately seem as thumbnails in Notion database views.

I've observed that typically it really works, particularly once I embed the picture earlier than writing any textual content on the web page. Even so, this conduct doesn't appear constant, as a result of in lots of circumstances the thumbnail merely doesn't seem.

My query is: is that this a Notion bug or is there a particular method to insert the picture in order that it's acknowledged as a thumbnail within the database?

If anybody is aware of if there's a rule for this, or some limitation of Notion with embeds, I might admire it.

In this print screen, you may see that the same embedded image link worked in the first page, but not the second, and it was a copy and paste.

The hyperlink used on this instance was https://static.wikia.nocookie.net/whitewolf/images/f/fa/1999ReckoningLogo.png
