Greater Manchester Police (GMP) has appealed for Constance Marten to make contact and seek medical assistance.
Ms Marten, Mark Gordon and their child have been missing since their vehicle broke down near junction 4 of the M61, near Bolton, on Thursday.
The image is thought to show the new mother outside Harwich Port in Essex.
After breaking down, GMP said the family left the vehicle safely and walked towards Anchor Lane bridge which links the Highfield and Little Hulton areas.

GMP believes the new image shows Ms Marten, wrapped in a large red scarf, outside Harwich Port at 09:00 GMT, more than 250 miles (400km) away.
“Our concern is make sure that Constance, Mark and baby are safe and well,” the force said.
It said evidence suggests Ms Marten had “very recently given birth and neither her or the baby have been assessed by medical professionals”.
GMP said Ms Marten and Mr Gordon were both originally from London.
Mr Gordon was described as wearing dark clothing while Ms Marten was wearing a burgundy coat. The baby was swaddled.
