Hmm, after a bit of testing I find that the MAX_FILE_SIZE tag is useless to 
say the least (probably because no browsers support it?)

In all of NN, Opera, IE having the tag does /not/ prevent the file from being 
uploaded. Thus if I set MAX_FILE_SIZE to 100000 (100K) and upload a 5MB file 
what happens is:

1) you still have to wait for the whole 5MB to be uploaded
2) php sees the MAX_FILE_SIZE setting is exceeded then discards the file

If anyone wants to run their own tests here's my test script:

    <form enctype="multipart/form-data" action="<? echo $z_PHP_SELF ?>" 
      <input type="hidden" name="MAX_FILE_SIZE" value="1000000">
      <table border='0'>
        <tr valign="top">
          <td align="right">Gimme a file</td>
          <td align="left"><input type="file" name="file" size=60></td>
      <input type="submit" name="action" value="GO">
    $file_size     = $HTTP_POST_FILES['file']['size'];
    $tmp_filename  = $HTTP_POST_FILES['file']['tmp_name'];
