Have you gained weight recently? If not, it may just be the angle of the photo or your posture. If the photo was taken at a lower angle than your face it can make it look like a jowl. If you chin was tucked in as opposed to jutting out, it can make it look like a jowl. Practice with a few pictures to see what the issue was.
Otherwise, there are some facial toning exercises (you can google them).
