I manage a WordPress site for a band and Ultimate FB Plugin updates their fan page when we post to the blog.
Problem is when I post to the blog it updates the fan page but uses my photo as I'm posting to the wall.
We want the website/logo from the band to make the post/update to the wall not me personally.
The Open Graph controls the "featured image" for Facebook but it doesn't change the face of the person posting.
I hope I'm making sense but when we setup a website to post to a FB wall we want the site to appear to be doing the updates NOT the person.
