I did want to mention a recent test that I did where in addition to the call to action below, I placed a link in the text area above the image. The result out of 5000 clicks? Only 5% of the clicks came from the link up top. 95% of the clicks came from the call to action below. I believe that people are becoming conditioned to engage that section of an ad.
It's valuable. Since the image was taken on a beautiful day, it looks like an ideal place to be -- especially to those of us viewing it from our office desks. It also clearly tells you the cost of the ticket so you know before you click. (This is also good for the advertiser: By including the price, the ad allows users to self-select based on whether they can afford the ticket. If they can't afford it, they won't click through, thus saving the advertiser money on unqualified clicks.) How do you know who is tracking you on Facebook?
