Adobe PDF cover image converts from photo image to generic PDF icon in Mac mail

Hi all, In Mac mail, I want to show a photo image on my Adobe PDF fille. but when I drag  the file (which on the Mac desktop shows the photo image as the cover - not the PDF logo) for some reason it converts to the PDF logo in my mail app. How do I keep the cover photo on my PDF in Mac mail and not use the PDF logo? Is this possible?

I would think that this is a macOS issue. And an issue of the mailing program. And if you solve this, there is no guarantee that the receiving side will be able to look at the picture.
