I read this yesterday and I was thinking this is kind of a trick question... I think OH Breeder summed it up pretty well. There are a lot more factors that go in to what one is worth than what she looks like in a couple of photos, especially if the photos don't exactly represent her. I too am wondering if the heifer might not be better than she looks in that particular profile shot. You can give somebody an idea of what she kind of looks like, but using a picture that doesn't flatter a pretty good heifer doesn't do you any favors. When I'm trying sell sight unseen cattle, I would much rather tell somebody, "That's a flattering picture of her" and then explain why I think so than "That picture doesn't do her justice" and try to convince them she's much better than what they're seeing.
This picture of your heifer makes her look like she has some good parts. Get a better picture and I think she'll look like she puts those parts together a little nicer. The easy answer to your question is they're worth whatever you can get for em! If they're worth more than that to you, then either you have to figure out how to convey something to your prospective buyers they aren't considering as value or worth, or your not being completely objective in assigning value. I think there are more people who think they're cattle are worth more than they get than people who get more than they think they're worth!
