Sostituisci sempre a quella pag. html il codice che posto e vedrai cosa intendo...è una gallery tipo questa postata, e come vedi con lo scroll, la foto in grande viene visualizzata sempre a sinistra e non dov'è la foto....come faccio a dire alla foto grande di posizionarsi sempre al centro della pagina anche scrollando tutto a destra?

Grazie ancora per l'attenzione e la pazienza
