Wow! That's a real image
I tracked that image down through the JPL Rover home page, to Malin Space Science Systems, and it is indeed a real MGS image captured the 19th. The lander is so much brighter than its surroundings that those pixels are saturated, making it very easy to spot. The image was taken using that new technique for pitching and rolling the orbiter to increase the resolution to--get this!--50 cm/pixel.
Here's the MSSS page. The full size image without annotations is pretty impressive.
