Gallery app looking for local SMB shares?

Please enlighten me: it looks like my GS3's Gallery app is identifying users on my network, from my desktop (CFJS-DT) and my wife's notebook (PKJS-NB).

Unfortunately I don't know what's going on or how to configure that, moreover I don't see any pictures from the scanned computers (see picture below).

Any ideas?



Thanks in advance.
