Unfortunately Kendor the answer must be a 'I Don't Know'. Why?
Because I don't know - silly

However I can assure you that if life is found on Mars one of two scenarios will play out.
1. From the time of discovery onward NASA, JLP and the Governments of Earth, evil and dark as they are will bury the data and present us with cleaned up imaged or better, with movie stage images of what mars (or wherever they find life) is supposed to (by their thinking) look like.
Contrary to the lovely moronic folk who bring us such things as the Moon Landing Hoax theory and Face on Mars theory, there will be NO images released that would even remotely look like anything that those theories propose. Meaning that this particular photo would never have been released since it remotely looks like life on Mars.
2. Life is found, NASA, JPL, Governments of Earth being the benevolent and scientific creations that they are immediately spread the world to every nook and cranny on earth that "We are not Alone!!!!". Awards and ceremonies and of course a petition for trillions of dollars for a flagging space program would be handed over to send even more rovers, and probes and even people to, in this case, Mars.
Even if it was something as insignificant as a single brick that really supported the past existence of a civilization, NASA, JPL, and all of the other agencies would be suddenly rich beyond their wildest dreams because they would make most certain that public attention was not only focused on The Brick, but also that the people would be programed to understand the need for a billion dollar bolt driving set to help build the trillion dollar super space ship with deluxe auto nav remote pressurized buggy probe, and of course all of their back ups because, even though Mars is so far away and all of that, finding proof that there was another people even a billion years ago is worthy of our attention.
We can not have it both ways, meaning a corrupt evil government hiding aliens and alien artifacts 'accidentally' letting a photo (or more like thousands of photos) slip through with 'evidence' that John Whats his name can 'easily' render to show the ancient strong holds of the Barsoom peoples and of course their equivalent of the Giza Plataea.
If NASA, JPL, etcetera ad naseum were hiding something from us, you can rest assured that not one single photo would 'leak' out. And even if one did, you can be most certain that it would be a one time mistake, not a repeatable one that continues to feed the conspiracy theories of ET.
While I do not know what those objects are in the photo(s) I know what they are not - signs of life.
