No offense, but that?s kind of a surprising question. The number of pictures of Natalie Portman on the internet must number well into the five figures. And according to Google she?s been in 55 movies. Why do you think she?d be hard to find? Or did I misunderstand your question?
I meant finding the particular photo that was in the ad. I'm sure that, typically, I wasn't clear in what I was asking. I did a Google search for pictures ("images") of her, and Lord know how many turned up. I believe there are ways to search for a particular image of somebody, but that's beyond my technical knowledge. I wasn't able to search for the photo in the ad, and there were way too many to "eyeball." The closest I came to the photo that was in the ad was the photo that accompanied the Wikipedia article about her.
