As you've probably surmised, this isn't a photo of the Swinging Bridge, but of the view upstream to Yosemite Falls from the Swinging Bridge. The bridge is only a few steps away from the Swinging Bridge parking area along Southside Drive. The bridge is also a bike path, so keep an eye out for cyclists while you're checking out the views here.
The rafters lazing down the Merced River in this photo probably rented their craft at Curry Village. For $27.50 per person, you get a raft and a ride back to Curry Village at the end of the float.
See the map below for the locations of the Swinging Bridge (the orange balloon) and Yosemite Falls (the blue balloon), and see also, if you're so inclined, these Google Street Views of the bridge parking area (the bridge is visible in the background) and the bridge itself.
