This issue is strange to me

[Dknelson]

If I sent somebody a link to my site via text message, they see the link as the icon from my site.  If anybody posts a link to my site on Facebook or through Facebook messenger, it links to the site correctly but shows the picture of a guy that I've never seen.  Can. somebody tell me why that is happening?  Here is what it shows.

The picture of this guy is probably taken from the avatar.

Adding og:image via ACP's tag editor should fix the problem.

<meta property="og:image" content="link_to_your_logo_or_image" />

You can also set a global sharer image.
