This is what I get when I try to change an exif tag of the photo, such
as typing something in the comment box, or rotating the photo.
Exif.ExifData:Save just crashes..
Any ideas?

If a set of independent equally distributed random variates defined on
the same probability space have a finite mean and variance, then their
sum approximates the normal distribution.
