supersized background

[ombra1975]

Salve a tutti

Qualcuno di voi immagino già conoscerà la script jquery che rende possibile adattare una sequenza di immagini di sfondo alla finestra del browser.

Ho scaricato i file a QUESTO INDIRIZZO

Sono riuscito ad inserirlo nella mia pagina però...c'è sempre un però...

Mi chiedo se sia possibile fare una cosa
Premettiamo che (nel mio file test.htm) questa parte di codice individua la sequenza di immagini;

<div id="supersize">
	[img]bkg1.jpg[/img]
	[img]bkg2.jpg[/img]
        [img]bkg3.jpg[/img]

</div>

Io vorrei invece creare N sequenze di immagini dove il codice sarebbe:

<div id="supersize1">
	[img]bkg1_1.jpg[/img]
	[img]bkg1_2.jpg[/img]
        [img]bkg1_3.jpg[/img]

</div>


<div id="supersize2">
	[img]bkg2_1.jpg[/img]
	[img]bkg2_2.jpg[/img]
        [img]bkg2_3.jpg[/img]

</div>

...ecc ecc

Nello specifico vorrei che di default fosse visibile solo "supersize1" e che al click su mio tasto di navigazione mi nascondesse "supersize1" e mostrasse "supersize2"

Qualcuno mi dice, consiglia da dove cominciare?

Come nascondere i div e mosrarne un altro non c'è problema, la cosa difficile è modificare il js che crea la sequenza di immagini di sfondo...è qui che devo intervenire giusto?
