Those large HiRISE photos are made from 8 pairs of image strips, each pair from one sensor.
The part of the photo where we can see those "dots" is strip 1 from the RED9 CCD, and that's where all the "dots" appear.
You can see below a GIF image (with no loss of detail, GIF compression is lossless) that shows the first 1000 lines of that image strip.
Strip 0 also has some noise problems, but as pronounced as those from strip 1.
As the image is not map-projected, it's "upside down".
Edit: I forgot to say that the GIFs are made from the IMG files available
