Malaysia's transport ministry on Sunday said the images show what could be debris in what investigators say is the southern corridor of the massive search area in the southern Indian Ocean.
"Malaysia immediately relayed these images to the Australian rescue co-ordination centre," Malaysia's transport ministry said in a statement.
Australian and Chinese officials earlier captured satellite images of objects they thought could be pieces of the Boeing 777 that vanished on March 8 with 239 passengers and crew on board as it was travelling from Kuala Lumpur to Beijing.
Planes and ships have crisscrossed the area southwest of Perth, Australia for most of the week but still haven't found anything tied to Flight 370.
Eight search planes departed from a military base near Perth on Sunday to scour an area about 2,500 kilometres away in an extremely isolated part of the ocean.
Air and sea searches since Thursday have not produced any results.
Planes and a ship scrambled Sunday to find a pallet and other debris. The pallet was spotted by a search plane Saturday, but has not been closely examined. Wooden pallets are commonly used in shipping, but can also be used in cargo containers carried on planes.
