Define 1st image in post as open graph object?

[jl255]

Is that possible? Or is there a way to define an image as open graph object through bb code? This is so that when someone shares a thread in Facebook, the 1st image shown in the thread is what is displayed in Facebook instead of the forum logo or an avatar.

Maybe see what you can do with this https://vborg.vbsupport.ru/showthread.php?t=300221 or if the developer has a version for vb3
