Thanks, but in GWT I see all theese links and each one show the same page
/gallery/showphoto.php?photo=312&cat=views&limit=views
/gallery/showphoto.php?photo=312&date=1208455822
/gallery/showphoto.php?photo=312&date=1210060375
/gallery/showphoto.php?photo=312&date=1211216453
/gallery/showphoto.php?photo=312&date=1254517322
etc.
so I must add a rel=canonical instruction. How can I add this?
Moreover: trying to switch to
seo mode, I see blank page: is missing some file?
