ho finalmente trovato al gallery che cercavo!
mi serviva qualcosa che facesse vedere le immagini di picasa degli album nascosi
il componente è appunto questo:
http://extensions.joomla.org/extensions/external-contents/photo-channels/8941/detailsunico problemino che ha è che visualizza solo le immagini jpg
le png, gif, bmp, o altro insomma non lo fa vedere...
il problema è nel sorgente, qualcuno riesce a sistemarlo (e se ha vogli anche a comunicare il problema e la soluzione all'autore che io non so come si faccia...)
ecco il sorgente:
