this is a file system issue rather than a web server issue.
as far as the file system is concerned, everything is a subdirectory of the root directory, so 1500+ subdirectories is trivial.
Thanks for reply.
Am I correct in thinking that images would, per standard practice, go into (probably subdirectories of ) the Apache images directory? The intention is to place all of these 1500 folders into one product images folder. Could too many items in one directory cause any performance issues and if so, what's a safe limit?
