Ciao a tutti, volevo sapere se qualcuno sa risolvermi questo piccolo problema che ho con il componente di Yootheme "Zoo"
Ho creato sul componente una nuova applicazione dove ho definito Textare, Immagini . . .
Tuttavia questo componente mi permette di inserire solo immagini hostate sul mio server perchè aggiunge di base la "path" del mio dominio, qualcuno ha idea di come io possa caricare immagini non hostate sul mio server?
Penso che ciò che gestisca questa funzione sia il file /media/zoo/elements/image/image.php
