A user at it.wp reports that he could not successfully replace a picture with this edit https://it.wikipedia.org/w/index.php?title=Castello_di_Serravalle_%28Bosa%29&diff=61339995&oldid=61339964, although he managed to do so on other occasions, so he knows how it works.
He just replaced Bosa Castle.jpg with Veduta del Castello.JPG, and correctly previewed the latter.
But upon saving, the pic was gone - the field is empty. He tried again later, and managed to reproduce this behavior.
Other users, including me, are not able to reproduce this.
He's using Chrome with Snow Leopard. Thanks.
