height: 62px;
margin: 14px 0px;
background: url(img/0309input.jpg);

}
.button input {
height: 200px;
position: absolute; /* for easy positioning of the field */
top: 0; /* initial coordinates */

Actually a question: CHANT & WTF?

What is this C:\\fakepath and where does it come from? The usual, not stylized, file input Opera display correct the full path from the root...

UPD:
Just checked on computers with Win7, WinXP, same thing.

UPD 2:
Have done so:
function str_replace(search, replace, subject) {
return subject.split(search).join(replace);
}

$("#photo").change(function() {
var newpath = str_replace("C:\\\\fakepath\\\\", ", $("#photo").val());
$("#filename").text(newpath);
});

Works.
However, shocked by the presence of such "security trimmings" or such a "compatibility tool", whatever. I don't remember how many sites have used this method of styling the input... it's now on them everywhere fakepath? Hmm...
