I'm confuded. Original data are available in format of Table only.
IMG files do not show original data, they are double in size and with ugly artifacts (for example, image 1204, see left top and left bottom corners).

As with all PDS data, you can check the DOCUMENT folder to find answers to questions about images. I don't have time to download and read, but it looks like this might be a source of answers:

What you've shown is a classic case of digital number (DN) clipping back to zero. This can happen if the software incorrectly assumes incorrect valid ranges representing brightness - note that only the brightest areas are clipped.

The clipped data may be saturated in the original data and have been "masked" to zero, flagging it as invalid.
