Based on the first photo, I think that's a 19" or 20" frame, which would be a "large" by Specialized's scheme. At 6'4", it's probably still be a size too small to be ideal for you.
A couple other thoughts:
1. a major-name full-suspension bike will be an elevated theft risk on a college campus. If you get it, don't skimp on your lock. A full-rigid old Rockhopper or Hardrock would be a lower risk.
2. if you need to ship the bike to its destination, be aware that shipping can be >$125 for a large bike in a bike box, plus you'll pay to have it packed. That's over half the initial cost of the bike, it might be better to buy one locally.
