id: identificativo della gallery
idcontenitore: id del div che conterrą le imagini
resize_contenitore: se si vuole adattare il contenitore alla foto
animations: tipo di animazione
mostra_titolo: se mostrare titolo e descrizione della foto

play_on_load: se si vuole far partire lo slide al caricamento della pagina
stop_on_manual_change: stoppare lo slide al cambio manuale delle immagini

$().DDSlideShowStopTime(id); stoppa il cambio automatico delle immagini
$().DDSlideShowPlayTime(id); avvia lo slide automatico
$().DDSlideShowNextImage(id); immagine successiva
$().DDSlideShowPrevImage(id); immagine precedente
$().DDSlideShowGetDescription(id); restituisce titolo e descrizione del'imagine
$().DDSlideShowGetUrl(id); restituisce l'url
$().DDSlideShowGetId(id); restituisce l'id
