I've seen most of her publicly posted pictures, all that I could find (the lions share thereof unpostable here due to her chronology at the time of the snap)... There are a few archives of her images out there.
The way she appeared over the time range was consistently growth-plausible, in context and form, to my eye. I think it's possible that some photos might have been tweaked against imperfections, but my impression is that the bulk of it all is real. I find it unlikely that anyone would significantly morph and post so many pictures of a girl at her age at the time, maintain consistency, And include all of those group photos with her peers. A significant proportion of those photos were with other people, and if they were all notably falsified - I would expect there would have been some kind of outcry and news-worthiness. The way modern media searches for and targets any kind of impropriety - we probably would have heard of such a thing.
Just IMHO.
