The breakthough was reported by the Australian Safety Transportation Safety Board (ATSB), which led a fruitless two-year, £97 million, search for the Boeing 777 after the aircraft went missing in March 2014.
The four images were taken in an area of about 25,000 square kilometres which the ATSB believes may hold the jet but was not searched as it is to the north of the official 120,000-square-kilometer search zone.
The Boeing 777 disappeared en route from Kuala Lumpur to Beijing on March 8, 2014 with 239 people aboard, and continued to fly for more than six hours after contact was lost.
He said that while the latest report was encouraging, the object had "not been definitely identified" from MH370.
"We measured its drift characteristics after modifying it to match the damaged one retrieved from Ile de la Reunion", the report says.
The Australian Transport Safety Bureau's search for MH370 was suspended indefinitely in January after a deep sea sonar scan in the southern Indian Ocean failed to find any trace of the plane that vanished in 2014.
The images were received by Australian authorities in March this year - three years after they were taken.

Sort of how you would imagine an outdoor auction to be, a group of all-white bidders sat in rows of neatly-lined chairs. OBJ also responded to the video after a fan asked him about his thoughts, stating that he was simply, "speechless".
"Geoscience Australia identified a number of objects in the satellite imagery which have been classified as probably man-made".
The CSIRO pinpointed the likely locations by reviewing satellite images provided by the French military intelligence service and France's national space agency, CNES, which showed 70 pieces of debris.
But Malaysian transport minister Dato Sri Liow Tiong said the newly defined area was not enough to go on and it was hoped debris drift modelling would help narrow the plane's location.
The details of that work are described in the report Summary of imagery analyses for non-natural objects in support of the search for Flight MH370: Results from the analysis of imagery from the PLEIADES 1A satellite undertaken by Geoscience Australia.
Mr Hood said at the time that it was "highly likely" that the new area identified by experts contained the aircraft.
Al Jazeera's Andrew Thomas, reporting from Sydney, said the proposed locations were "no longer vague" and "puts pressire on the authorities, Malaysia in particular, to restart the search".
