Hello!
I have Coppermine 1.6 but the problem was the same with 1.5.
I copy the link of a page for example https://www.fotoferrovie.info/displayimage.php?album=959&pid=23759#top_display_media
I paste it into FB.
In a first moment it shows the image corrctly (screenshot_29).
Then when I publish the message there is no more the image (screeenshot_30).
Can someone help me?
Tkx in advance!
Facebook probably doesn't want users to embed a whole web page into their interface/pages.
(not a CPG issue, I think)
You could try to upload the picture and assign a link to that page perhaps?
It also occurs to me. It's funny because Facebook does show the preview of my home page, but when I share a gallery link (an image), it shows the preview until I finally post the message, where the image doesn't show up.
For some reason, Facebook doesn't like anything CPG linked to, but it's fine with displaying a simple html page with images.
CPG image page link:

I don't think it has a solution, it's not a CPG problem.
