Hi john

This is strange because I have some old pictures and I want to rename  
them based on their creation
time and not modification time. So I was really paying attention  
because I really do not want to
lose such information before my renaming (you know young kids....).
I will check with the latest mac VM.

John do you know if we can set also such information. So far I only  
find read only version
and I have pictures with no creation time but I know it and I would  
like to treat all my photos
to be independent of iPhoto metadata crap.
