Question in Brief: Is there a way to reassign the author of an image already uploaded into the gallery? If so, how?
Some background: I've recently become the administrator of a site for a client. The site was inherited as part of a business acquisition and they deleted the primary user account associated with the previous owner. They didn't reassign the posts, pages, etc to a current user.
Needless to say, this kicked up a whole heap of author-linked content 403 errors when Google crawled the site. I've been able to change the post and page authors, but can't seem to do the same for the images uploaded under that user name. These, too, are kicking back 403 codes. I found a plug-in here: http://wordpress.org/extend/plugins/media-author/. but I"m leery of unsupported plug-ins.
