French President Emmanuel Macron is now in Nice where a minute's silence has been held for those that were killed in a terror attack a year ago.
The prosecutor asked the court to "order the (magazine's) withdrawal from sale" as well as a "ban on publication in all formats, particularly online".
A lorry killed 86 people when it drove into crowds celebrating Bastille Day.
In its ruling, the court said that victims, dead or fleeing death, were identifiable by their clothing and the images capturing the truck as it moved down the Promenade des Anglais provided "nothing new to the public's right to legitimate information about the events", according to a portion of the decision tweeted by a lawyer for a victims group.
A judge is to rule on the request at 2pm French time.
Victims' organizations had denounced the photos depicting scenes - camera grabs from video surveillance film - of the carnage on a main beachside walkway on July 14, 2016, when a 19-ton truck barreled into celebrating crowds.
The magazine has faced legal action and censure several times before over the publication of private and sensitive images and interviews, including what it claimed was the last interview with Princess Diana before she was killed in a 1997 auto crash in the French capital. He said they images are taken from afar, without identifying anyone and without "attacking their dignity".
The Nice footage was the subject of a previous controversy after police called on city authorities to delete the video surveillance to avoid the "uncontrolled sharing" of images.
Eric Lawyer, a lawyer for the association of victims, FENVAC, said the publication was "illegal" and was only proceeding with the scoop "to be sensationalist".
The mayor of Nice, Christian Estrosi, also criticised Paris Match for publishing the images on the eve of the first anniversary of the attack.
The attack, claimed by so-called Islamic State, was part of a wave of jihadist-inspired murders in France.
