/* 
    Greetings!!!

    file size before implementing test14.php 
    newmail.gif(915)
    -> file size after implementing test14.php
    newmail_out.gif(946)

    It operates correctly in php version 3.0.
    But, It oprerates incorrectly in php versin 4.0.
    
    and, if file type is *.txt, this program is operates 
    correctly
    
    I thinks that fread() or fwrite() is problem.    

    please, tell me solution of this problem.
    I don't know that i don't know.
