 </head>

   <table>

     </tr><tr>
      <td><label for="image_filename">Upload Image:</label></td>

    <p>Select your destination:</p>
    <table>
     </tr><tr>
      <td><input type="radio" id="destination_1" name="destination" value ="beach" /></td>
      <td><label for="destination_1"><img src="images/beach.jpg"></label></td>
     </tr><tr>
      <td><input type="radio" id="destination_2" name="destination" value ="golfcourse" /></td>
      <td><label for="destination_2"><img src="images/golfcourse.jpg">
     </label></td>
     </tr><tr>
      <td><input type="radio" id="destination_3" name="destination" value ="mountains" /></td>
      <td><label for="destination_3"><img src="images/mountains.jpg"></label>
      </td>
     </tr>
    </table>
    <p style="text-align: center">
     <input type="submit" name="Submit" value="Submit" />
     <input type="reset" value="Clear Form" /></p>
    </form>
   </body>
  </html>

And upload_image.php file is :

Code:

<?php
// Filtra le variabili in arrivo
$image_caption = (isset($_POST['image_caption'])) ? $_POST['image_caption'] : '';
$image_username = (isset($_POST['image_username'])) ? $_POST['image_username'] : 'Anonymous';
$destination = $_POST['destination'];
$image_tempname = $_FILES['image_filename']['name'];
$today = date('Y-m-d');

// Modificare questo percorso in base alla directory che contiene le immagini
$dir ='C:/Programmi/Apache Software Foundation/Apache2.2/htdocs/images';

$image_name = $dir . $image_tempname;

if (move_uploaded_file($_FILES['image_filename']['tmp_name'], $image_name))
{
   // Recupera le informazioni sull'immagine che sta per essere inviata
   list($width, $height, $type, $attr) = getimagesize($image_name);
   
   if ($type != IMAGETYPE_JPEG) {
       echo '<p><strong>Sorry, but the file you uploaded was not a JPG ' .
            'file.<br/>Please hit your back button and try again.</strong></p>';
   } else {
      // L'immagine Ã¨ accettabile, si puÃ² procedere
       $dest_image_name = $dir . $destination . '.jpg';

       $image = imagecreatefromjpeg($image_name);
       list($width2, $height2, $type2, $attr2) = getimagesize($dest_image_name);

       $image2 = imagecreatefromjpeg($dest_image_name);
       imagecopymerge ($image2, $image, 0,0,0, 0, $width, $height, 100);
   }

   header('Content-type:image/jpeg');
   imagejpeg($image2);
}
?>

When first file call upload_image.php there is next Error message:
Warning: getimagesize(C:/Programmi/Apache Software Foundation/Apache2.2/htdocs/imagesbeach.jpg) [function.getimagesize]: failed to open stream: No such file or directory in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\upload_image.php on line 27

Tried your code, I had to mofify couple of things to make sure the images actually exist. Check the following:
1) Is C:/Programmi/Apache Software Foundation/Apache2.2/htdocs where you installed your httpd?
2) Is imagesbeach.jpg the exact name of your image? (There are three images, and you have to check and make sure that they all named as the program expected.)

This line is suspicious (unless that's intended and you did name your files like imagebeach.jpg):

Code:

$dir ='C:/Programmi/Apache Software Foundation/Apache2.2/htdocs/images'

You probably meant (I added a / at the end of the string):

Code:

$dir ='C:/Programmi/Apache Software Foundation/Apache2.2/htdocs/images/'

Or modify the following line:

Code:

       $dest_image_name = $dir . $destination . '.jpg';

And change it to:

Code:

       $dest_image_name = $dir . '/' . $destination . '.jpg';

One way or another you have to add that /, otherwise 'image' won't appear as a folder name but part of your image's name (like imagebeach.jpg)
