    readfile and images

    I'm trying to replace <IMG SRC="some image"> with the usage of readfile, but
    without luck. I have seen examples like this:

    header ('Content-length: ' .filesize($imag e_file));
    header ('Content-type: image/jpeg');
    readfile ($image_file);

    This works OK unless you have modified the header before. What I like to do
    is to display the image *within* HTML codes, something like:

    <HTML><HEADER>b lablabla</HEADER><BODY>
    <?php
    echo "This is image $image_file:<BR >";
    readfile ($image_file);
    ?>

    But if I try to use the readfile as show above, I only get garbage... (as
    expected). So... how can I replace a <IMG..> statement with the use of
    readfile?

      I got it... I have to use <IMG SRC=some-php-script.php?arg= filename> and
      then use the code shown at the top.
