[Mediawiki-l] How to configure LocalSettings.php when using symlinks

[Ling Hwee Ting]

Hi, I have two websites on the same topic and I am trying to use one
image folder so that both websites can share the same images. I have
used symlinks for one website (kesihatan) pointing to the image folder
of the other website (health). What else do I need to do? I tried:

$wgUploadPath       = "images";
$wgUploadDirectory  = "images";
$wgAllowExternalImages = true;

but it is not working. I also tried

   $wgUploadPath = "../health/images";

Any help deeply appreciated.
