This is a Crusader image [1096]...
(Oh, I get it, they both have 'plumes' on helmets, silly me!)
Nope. Neither image shows what a Crusader looked like. The first is obviously a Roman, as was pointed out already. With the latter one, full plate armor was only common around 1400-1550. By then the Crusades were over, unless you count the final war against the Moors in Spain (1481-1492), and the “Baltic Crusade” led by Germans of the Teutonic Order, against the pagan/Catholic Lithuanians and Orthodox Russians.
For the Crusaders you are probably thinking of (those going to the Middle East in the 11th-13th centuries), the armor usually worn was chain mail, topped by a steel cap with a nose guard. And there definitely has to be a cross on the outfit somewhere!
