The following article might be of some help. An interview with Clara Torres who took the photo.

The picture was taken through the windscreen of a car in Morocco

Clara Torres: Took the original picture of the girl.
"As soon as I took the photo we were struck by the little girl, who was very blonde. I was on a trip in Morocco and took many pictures, just random ones. This was one of those pictures. I remember being struck by her and even mentioned the name Madeleine to my boyfriend.
"But I didn't think too much of it at the time because although it is uncommon it is not unusual to get blonde people in that part of the world. Also, I didn't think Madeleine could be in Morocco.
"It was only when I got home and saw the news on Monday about two possible sightings of Madeleine in Morocco that I remembered the picture and went through my photos. When I saw it for the second time and focused in on the child's face, I realised it could be her.
