I have no idea if this is a support issue, or just a general question, so feel free to move if necessary.
On one of my clients sites, the image that comes up when he shares the link in Facebook is an Advertisment from his forum.. nothing to do with the actual clients site at all.
Is there any possible thing that can be done to change this image? Is it indeed anything to do with Xenforo...
Any help or advice is appreciated
