and these are also configured on B, the internal wiki? I read through the description on the below links, but I can't make out which directory on what server I need to configure.
Yes, you tell B which db A uses (by default tries to access with the same db login as B's) and on which local folder (for B) the images are (for creating thumbnails). It's a folder seen from B's server, so if A is on another computer you would mount it on B using a remote filesystem like NFS.
