Which filesystems? I know ext2 used to have issues with many-thousands
of files in one directory, but that was a directory scanning issue
rather than file reading.

No. Otherwise the filesystem people would build their filesystems on top
of PostgreSQL not the other way around. Of course, if you want image
updates to be part of a database transaction, then it might be worth
storing them in the database.

Look into having a separate server (process or actual hardware) to
handle requests for static text and images. Keep the Java server for
actually processing data.
