Open Graph

[Andy]

Open Graph is used by Facebook and Twitter when you create a new post. When you paste a URL the Open Graph function will get the image from your forum.

You can use this add-on to get the first embedded image from a thread:

So if you want to share a thread on Facebook or twitter, you copy the thread URL and paste it into Facebook or Twitter.

Sharing a link on Facebook or Twitter where there isn't an image. By default XenForo will try to use your logo. However this is generally not desirable. So XenForo has a Style option specifically for Open Graph.

Admin control panel -> Style properties -> Basic options -> Metadata logo URL

I suggest you make and image which is 200x200 and upload it to the above path. This image will be used, unless you're creating a new post using a thread URL.
