You can use the rover itself to judge the relative size of rocks and other things. Here's an image from Curiosity's hazcam, located at the bottom front of the rover: mars.jpl.nasa.gov...
The "wrinkled" area and many rocks nearby fit between Curiosity's wheels!
The instrument turret at the end of the robotic arm is another good comparison: mars.jpl.nasa.gov...
Here's a gif animation of Curiosity's movements and activities over the last few Sols, as seen by the navcam. Keep in mind that Curiosity is car-sized. Your area of interest is shown from Sol 165: www.marspages.eu...edit on 27-1-2013 by wildespace because: (no reason given)

A number of these images involve stereopairs.
Because stereopairs require the two cameras to be a distance apart, and therefore provide co-ordinates the can be calculated from the point of convergence etc ... you could fairly accurately measure the size of objects in those photographs.
If NASA was lying about the size of the rocks, it would have to be in images not involving the stereopairs. It would probably be considerbly easier to just not photograph the suspect areas.

All the rest of the images apart from the one you posted, are from this image:

Photogrammetry is nothing new though, and hiding something like that it plain sight would be questionable.

I love you Armap!
Have I told you this recently? Person with photogrammetry app in their pocket, so dreamy. Haha

There's also a very wide variety of these un-natural shaped rocks and I find it strange as to why that would be, unless it had been molded/carved sometime in its past.
I recently heard that it takes up to 20 minutes for a image to be taken on the red planet before making its way online to the JPL website, hence why these objects are still in the images.
Additionally, the location of Curiosity is exactly where you would find remnants of what was once on the planet, it's one thing to claim that an ancient river may have eroded some of the rocks, which is fair enough, but it doesn't explain why some of the "rocks" are a different colour, that indicates, a different material.

Really all just conjecture though isn't it?

The trouble with all this conjecture is that you can go on 'conjecturing' until the cows come home but what we see in the images is not explained by NASA. For example the numerous mechanical-looking objects which litter the landscape and the 'things which move" between frames (and please dont tell me it is camera angle, cos it isnt).
