[JS] Rallentare una transizione jquery di uno slider...

[Glorifindel]

Vorrei fare in modo che lo slider presente in questo sito
http://osc4.template-help.com/wordpress_28312/

vada più piano, nel senso che l'effetto di fade va bene, ma deve proprio aspettare a cambiare "pagina" (ovvero immagine + relativi dati).

Finora sono riuscito unicamente a modificare la duration relativa alla velocità dell'effetto di fade, che non è ciò che voglio fare. Purtroppo per modificare la velocità con cui cambia il contenuto temo sia più difficile che variare semplicemente i millisecondi come per la duration dell'effetto appunto.

Infatti non sembra esserci nessun timer in millisecondi per eseguire il cambio di pagina, ma pare ci sia un ciclo if che gestisca il passaggio delle immagini con le info.

Vi metto il codice del file contenente la jquery; magari voi che avete un occhio sicuramente più esperto del mio potete consigliarmi cosa posso fare per rallentare lo slider (io di js so davvero nulla)

Spero di aver incollato la parte giusta da analizzare...
Incollarlo tutto era improponibile

Ma devi controllare la voce che richiama l'azione che valore imposta... se chiama default varia quel valore in quelle righe abbassandolo.
