I checked reference article and  I don't think it applies, but thanks
for trying.  I do not use AOL.  The photos were originally transfered
from a NIKON digital camera.  The ones that I'm unable to copy appear to
have been edited in some way, probably using "MicroSoft Photo Editor
3.0."  I've phased out using MicroSoft Photo Editor 3.0, even though it
is lightning fast because it was designed for much slower machines,
because I found that edited photos often no longer contained the
original meta data related to camera model and time the photo was taken.

I've contructed two test files that contain the identical imagery. One
can't be copied over the network.  The other, a derivative of the first,
can be copied over the network. The second was made by opening the first
with Digital Image and saving it with a different name.  When  the
"simple" properties of both files are examined using the copy of Windows
explorer resident on the machine they are resident, both  are blank.
When the "simple" properties of both files are examined over the network
using the copy of Windows Explorer on the new machine, the "simple"
properties view of the problem file has the message "Summary properties
are unavalable for the selected sources(s)."

Obviously, the problem files have corrupted meta data that interferes
with them being copied or viewed over a network.  I'm uncertain as to
how they got corrupted, although Microsoft Photo Editor 3.0 is
suspected.  I have a variety of image modifying programs, and I'm
uncertain as to which was used on which photos. Fortunately, Microsoft
Digital Image 10 does not seem to be the source of the problem AND my
new machine is fast enough that I'm not bothered by its large size.

IDEAS ON HOW TO "PURIFY" THE TROUBLESOME FILES ON A BULK BASIS WOULD BE
WELCOMED.

Its a bitch to be copying 1000 photos and have to go back individually
through the list of photos when the process stops, perhaps at photo
number 547.
