Hi Anas,

A feature request for the ability to show an actual image as a thumbnail in the Blazor FileManager component has already been submitted on our public feedback portal: Image Preview of Image Thumbnails in FileManager. Like the Image Library of the HTML Editor does. I voted for this on your behalf and raised the item's priority.

You can also subscribe to it to receive email notifications for future status updates.

In the meantime, if a workaround appears, I will share it in the comment section of the above-linked public post.

Regards,
