Here is the latest communication from Flickr.  There developers are going to
research, but they asked me to pass this information along.  If you look, you
will notice there is a difference between the tags in the PNG file and the JPG
file which was created from the PNG file.  My comments back to Flickr are at
the beginning of the note:

==========

Cris,

Thanks for the reply and again for your looking into this.  I would
expect to see some differences between the jpg and png files since
they are different formats.  However, what I am curious about is why
the EXIF information shows up in the png file here:

http://www.flickr.com/photos/9550073@N03/4001381895/meta -

which is the basepng.png file
in the photo stream and not in the png file which has the geo
information?  Also, its weird that the jpg version shows "unknown tag"
information, and displays alot of the info on Flickr whereas the png
version appears to show the info fine using exiftool below (with no
unknown tags) but basically shows nothing on Flickr.  I'll run this
information below by the developers and see what they say.  In the
meantime, I think we'll all be interested in what Flickr says.

Thanks again!
