Good question. I think it's safe to say that He wasn't the tall, blue-eyed guy that you often see depicted. I think it's actually a bit sacriligious (and racist) that He's usually being depicted as an aryan because it's highly unlikely that He was. You just wouldn't have found too many aryans in Palestine 2000 years ago.
Based on historical descriptions, scientists came to the conclusion that it's more likely that He looked something like this:
Rascist but probably necessary. In an a less enlightened age when contact with strangers, let alone strange looking foreigners was almost non existant, convincing ordinary folk that this was the son of The Almighty God might have been a tad hard. I think even now many people would have difficulty accepting that Jesus looks no different to the local kebab shop man.
But religious people don't have a monopoly on this kind of image manipulation. Remember your picture of the statue of Lennon from Cuba, where he's portrayed as a bare-footed peasant hero type chap (much more acceptable to a Communist regime than a borgouis (sp) millionaire driving around New York in limo's.)
