problema con spostamento immagini

[jackJJ]

$fullsize=imagecreatefrompng($save_path.$file_name); 
$fullsize_height=imagesy($fullsize);  
$fullsize_width=imagesx($fullsize);  
if($fullsize_height>312){ ... qui tutto funziona  
}
imagedestroy($fullsize); 
copy ($save_path.$file_name, "uploads/resize/$file_name");  
unlink($save_path.$file_name); 

era anche in rosso
