Maybe one way to this :

- let's say jour .jpg files are in /../......./imgs/ on BoxA
on BoxB:
- create a /../.../imgs2/ on BoxB
- copy your .jpg into .../img2/
- start an NFS server on BoxB (I don't work on FC4, but if you don't 
know anytaing about NFS, you can  look here 
<http://www.vanemery.com/Linux/NFSv4/NFSv4-no-rpcsec.html>
- share .../img2/ for BoxA

on BoxA
- create a .../.../imgs3
- mount .../img2/ on ..../img3/
- change your soft links in the html tree to .../img3/

No problem for users.

If they could wait some minutes, and if you have some BACKUP of your .jpg
on BoxA
- remove all .jpg from .../imgs/...
- mount .../img2/ on /imgs/
then you don't need to change soft links.
