I do not know what picture you refer to. I have no red lines on my picture, and the 3 rocks are clearly visible. Look at the far right where the 'panel' ends and it is clear that the 'panel' is simply the hard top crust of the surface which has been weathered.

Also I showed the picture (without telling them its from Mars) to a few colleagues and asked them if they can spot anything strange.
Everybody acknowledged that it looked like a piece of a rectangular sheet.
There are just so many objects that seem "unnatural".
