Hi, and thanks again for your patience.
After a ‘mumble-mumble’ night, finally I solved the problem.

Lines to insert in function.php:
//========== START ========================

//Custom Header & Background
add_custom_background();
// get current theme folder
$style_dir = get_stylesheet_directory() ;
// get header image size
list($width, $height, $type, $attr) = getimagesize($style_dir . ‘/images/header.jpg’);
//define( ‘NO_HEADER_TEXT’, true );
define(‘HEADER_TEXTCOLOR’, ‘fff’);
define(‘HEADER_IMAGE’, ‘%s/images/header.jpg’);
define(‘HEADER_IMAGE_WIDTH’, $width ) ; // read width of header image
define(‘HEADER_IMAGE_HEIGHT’, $height ) ; // read height of header image

// function for corrected WP site visualization
function header_style() {
?>
<style type=”text/css”>
YOUR CSS DIV CONTAINING HEADER IMAGE {
background: url(<?php header_image() ?>);
height: <?php echo HEADER_IMAGE_HEIGHT; ?>px;
width:<?php echo HEADER_IMAGE_WIDTH; ?>px;
}

YOUR CSS HEADER TITLE{
}
YOUR CSS HEADER SUBTITLE {
}
<?php
if ( ‘blank’ == get_header_textcolor() ) { ?>
YOUR CSS HEADER TITLE, YOUR CSS DIV CONTAINING HEADER IMAGE YOUR CSS HEADER SUBTITLE {
display: none;
}
<?php } else {
?>
YOUR CSS HEADER TITLE a, YOUR CSS HEADER SUBTITLE {
color:#<?php header_textcolor() ?>;
}
<?php } ?>
</style>
<?php
}

// function for corrected WP Dashboard visualization
function admin_header_style() {
?>
<style type=”text/css”>
#headimg{
background: url(<?php header_image() ?>) no-repeat;
height: <?php echo HEADER_IMAGE_HEIGHT; ?>px;
width:<?php echo HEADER_IMAGE_WIDTH; ?>px;
padding:0 0 0 18px;
font-family: arial;
}
#headimg h1{
padding-top:20px;
margin: 0;
}
#headimg h1 a, #desc{
color:#<?php header_textcolor() ?>;
text-decoration: none;
border-bottom: none;
}
#desc {
padding-top: 15px;
}
<?php if ( ‘blank’ == get_header_textcolor() ) { ?>
#headimg h1, #headimg #desc {
display: none;
}
#headimg h1 a, #headimg #desc {
color:#<?php echo HEADER_TEXTCOLOR ?>;
}
<?php } ?>
</style>
<?php
}
add_custom_image_header(‘header_style’, ‘admin_header_style’);

//========== END =====================

thanks for your patience.
The problem is that new uploaded header image (cropped-autumn4.jpg) go to in the folder wp-content/uploads/2011/01/
but css search background-image: url(“images/header.jpg”);
I cannot dinamically change the css, maybe…..

Thanks for your replay.
some changes:

$style_dir = get_stylesheet_directory() ;
list($width, $height, $type, $attr) = getimagesize($style_dir . ‘/images/header.jpg’);

and it works.

Now, the problem move to other side:
when I go to Appearence –> Header to change header image by browsing on my local disk and than –> ‘Upload’, the uploaded image stay in wp-content/uploads/2011/01/cropped-autumn4.jpg

Launching the browser the uploaded image is not present…uffa !

Suggestions ??
