Problem in direct linking of a sub album

I have a big g1 structure (130000 images in aprox 1000 albums) organized in albums and subalbums.
All this subalbums have direct link from the primary web site eg:

http://www.sorrisirandagi.it/gallery/view_album.php?set_albumName=album42

I've installed g2 in the gallery directory and moved the g1 in the same path but in g1 directory so:

http://www.sorrisirandagi.it/g1/view_album.php?set_albumName=album42

is working.

But the problem is that the orginal site points directly to gallery directory! and that in the original site there are thousands of links and is impossible to return to the old version of gallery...
I've activated the rewrite rules in the administration/configuration of g2 but the problem doesn't solve.
I've noticed that problem is relative to the fact that the album in the link in a sub-album infact the correct link in g2 version is:

http://www.sorrisirandagi.it/gallery/v/album148/album149/album42

Thaks to all in advance!
