multisite drupal

hi all,

I've been trying for some hours to get a multisite gallery, multisite drupal install working - i've successfully gotten a branch of a multisite gallery install to show up inside drupal properly, at least to the point of displaying image blocks etc - i'm running latest stable drupal and dev gallery- however, all the links within the gallery block and node point back to drupal root directory - perhaps my embed URI is off? i'm pretty familiar with both drupal and gallery having used them for years.

anybody know of a reason why this won't work at all? anybody been able to do it?
