No, these are quite a lot further on (about 2 miles more). The tarns are less over-used than guitar, but nothing like as spectacular as this place (centre of view I hope): Google maps camp
Basically, you continue up the JMT until about 500ft before it connects with the Whitney trail. These camping spots are slightly above the JMT, so much easier to see from above than in ascent. If you get to the Whitney trail junction you've gone too far, but turn around and you'll see the sites. If you drag the little person icon onto this google map, and position it on a spot just above the junction, you can look round and see the camping spots.
I've always (even in a dry year) found a good spring at this point, a bit beyond beyond the tarns. Hopefully centre frame as well: Google maps spring
