The picture is of a walk way between terminals. Started my day off badly when I spent almost a half an hour searching for the check in for aer lingus and when I finally found it I was minutes too late (still half an hour before departure). Paid 65 pounds to reschedule, which was almost double the original ticket price!
On the bright side I was able to reschedule my rental car at the facility here (saved like 1dollar by not using a pay phone, score!)
