Gary, this should be fun. I've been up to this area a lot. I believe there are 4 waterfalls, total, ending with Raven Cliff, which is the first picture in the link you posted. To get to the end of the trail, it is approximately 2.5 miles- the hike is fairly easy, but those carrying their 20x24 field camera might want to bring a long a couple of sherpas to help out!
Those not wishing to walk the full trail will still encounter some of the other scenic falls earlier in the walk. The trail has become pretty popular over the last ten years or so, but probably not so much so as to cause any inconvenience for photographers.
A couple of other "tourist" falls are close by, for anyone maybe wanting to make a two day outing- Dukes Creek Falls is within a mile or so of the trail head. It has a partially developed path to a platform looking down on the falls,
or, you can hike down a trail and get to a nice board walk at the base of the falls.
Of course, Anna Ruby Falls is close by. This is a paved 1/2 mile walk, up to a beautiful twin waterfall. Very touristy, but pretty view:
