Good afternoon now - and thanks.... I've been filtering through all the
responses. Sounds like I was incomplete with information but got the
right answer anyway.
Compression means different things to technical folks who work with this
stuff regularly vs. non-techies. In this case he's mixed up the term
compression with probably the automatic stuff that outlook does and
confused it with 'transferring' an image through email. I seem to
recall him saying once that whenever you transfer images through email
that there is a quality loss - I will go with wrong wrong wrong! Case
closed. Wrong is right....
Along the same lines zipping up a file or bunch of images with something
like WinZip or command line zip should not impact quality. So when the
receiver uncompresses and opens the zip file all should be well in lala
land. On some UNIX servers there is 'compress' and 'uncompress'.
When I talk about compression and images for the web that's the other
ballgame which my client and probably 90% of folks don't know about -
i.e. jpg is lossy, etc. My mistake if I inadvertently led you down that
path. The fingers sometimes move faster than the mind.
I have some useful file upload forms that I've set up for clients,
however on shared servers they typically set up fair limits of about
10MB to upload and/or post. Interestingly someone mentioned yousendit.
They actually used it to send me a 17MB .mov file. In any case I think
for this situation no loss of data is occurring in the file transfer.
AOL not involved here, so I can avoid that argument.
The Outlook smooch??? Is there where Outlook attempts to compress (not
lossy) or do whatever it must to send the file? A client tried to send
me something outrageous last week (which I never received) and the way
she described it was that Outlook was attempting to break the file down
into several pieces and send as a bunch of attachments. I was just a
little curious about how a mail reader other than Outlook (Tbird in my
case) magically fixes this on the receiving end. This is not a gotta
know....
Thanks, I am happy again...
