Add-on Og:image each thread for XF 2 using attachments

[OakleyForum]

This was an add-on on XF1 - but really is quite simple. Just want the og image tag to use any attachments in the thread plus the standard logo set in Style Properties, that way the sharer can use a relevant image and not just the logo all the time, but if there is no attachments the logo is there.

By coincidence I'm working on the same thing, here's a solution by @tohaitrieu that (so far on my test site) seems to work fine.

XF 2.0 - Set pictures from the post as thumbnail for Facebook and Twitter

Hi! Now all post sent to Twitter or Facebook via IFTTT go with the same og image. I saw that it was possible to use first images in a post and use them for posting in these sites...
