thanks , that explains why it was done this way. Probably ought to be  
checked, hopefully they've made a bit of progress in the intervening time.

imagemagick seems to have no trouble getting this info and it does depend  
on jpeg pkg.

Of course if there is an inadequacy in jpeglib they may have worked around  
it by reading the file header anyway, I'm pretty sure it's readily
