I'm not sure on what days these events occurred. There were a few days when these photographs could have been taken. You'll see June 4, June 5, and June 6 in the captions for what looks like the same event. Sometimes it's cloudy, sometimes the sun is out, and it's midday, and other times, the sun is out, and there are long shadows.
All I can say for certain is that American troops were in Rome in the first week of June 1944.

Twelve days after the Allied offensive was launched from the Anzio beachhead, Allied troops entered Rome on June 4th, and by the next day the occupation of the city was almost complete. Rome was spared the fate of becoming a battle ground by the strength of the Allied pressure south, which forced the Germans to withdraw hurriedly, leaving great quantities of war material behind them. As allied troops advanced through the streets, the Romans acclaimed them with overwhelming enthusiasm. Allied troops passing the Colosseum are cheered by the crowd, on June 4, 1944, in Rome.
