Use a shared file system such as NFS for upload storage.
Use some form of session management/balancing that ensures a client browser
that upload ends up on the same server immediately afterwards, and use
something like rsync to keep the image area in sync.
Shared storage is probably the better bet - perhaps with clever code that
tries a local disk first, then the shared storage if not found on local. If
found shared and not local, pull to local.
