Wing tip vortices and full burner illustrated here!
i can't see any afterburner in those photos, unless you're referring to the last picture which shows the heat plume from the heat of the engine but that still doesn't seem to be afterburner...
edit: or are you referring to the second picture? I can see how the inside of the exhaust appears a little bit red but I"m not sure if that is afterburner let alone full afterburner... I'd expect a much bigger and more obvious trail than that, maybe with some shock diamonds
