Description:
------------
I have a mysql database with a blob field, i  the page that return the binary image from an iframe, the first time that i call the parent, 2 in 3 times this message apears:

CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:

After this if i reload the page the image apears.


Reproduce code:
---------------
"parent.php"
...<td width="307"><div align="right">
<?php
	echo "<IFRAME SRC='imagens.php?id=$imagem' WIDTH='307' HEIGHT='230' FRAMEBORDER='0' name='img'  noresize marginheight='0' scrolling='no'></IFRAME>";
?>
</div></td>...

"imagens.php"
<?php
$id_img=$_REQUEST['id'];
if($id_img) {
   header( "Content-type: image/jpeg");
   $db_img="labsig";
   $mysql_access_img = mysql_connect("localhost");
   mysql_select_db($db_img, $mysql_access_img);
   
$result_img = mysql_query("SELECT imagem FROM imagem_projectos WHERE id=$id_img", $mysql_access_img);

$data_img = mysql_result($result_img,0,"imagem");
echo $data_img;
	
};	   
?>

Expected result:
----------------
I expected that when i load the parent the image loads, but it don't always load, only 1 in 3 times, or less.
