Gabby's parent's lawyer are asking Brian's lawyer to stop using her image. Basically accusing Brian's lawyer of promoting his business with Gabby's image is what I got from that.
And Brian's lawyer is basically saying that he has no control over Yelp and did not post her images or use them himself. As far as what I know from Yelp, I think that's right - I don't think the business has much control over what is there (other that to help populate information like web address and menus, or to post its own photos).
