se non ho capito male tu vorresti una cosa del tipo:
Codice PHP:
<html>
<head>
<title>Documento senza titolo</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-2">
<script language="JavaScript">
function show_image()
{
var element = document.getElementById("file");
var image = document.getElementById("image");
image.src = "file:///"+(element.value);
}
</script>
</head>
<body>
[img]immagini/no_img.gif[/img]
<form action="" method="post" enctype="multipart/form-data" name="form1">
<input type="file" id="file" name="file" onChange="show_image()">
</form>
</body>
</html>
non centra nulla con php......... ciao
