Upload e resize immagini

[softhare]

...allora prova così:

  // ottengo la larghezza e l'altezza dell'immagine originale   
        list($image_width, $image_height) = getimagesize($remote_file);   
        if($image_width>$max_upload_width || $image_height >$max_upload_height){   
            $proportions = $image_width/$image_height;   
            $new_width=$image_width; 
            $new_height=$image_height; 
            while($new_width>$max_upload_width || $new_height >$max_upload_height){  
             if($new_width>$max_upload_width){   
                 $new_width = $max_upload_width;   
                 $new_height = round($new_width/$proportions);   
             }         
             if($new_height>$max_upload_height){   
                 $new_height = $max_upload_height;   
                 $new_width = round($new_height*$proportions);   
              }      
}
