That's my experience too. I believe we had problems with DOS when we had more than 30.000 files but not Netware. Or was it the other way around :-) Senility. I suspect that Mark won't have that many pictures -- afterall he wants to print a report with the pictures.

I've never tried to work with more than 80.000 pictures. However I would think that storing the pictures directly in the tables is not an option anyhow because the size of the table would exceed 2.1 GB.

With Linux/Samba we had to be very careful accessing large directories of emails.
