Desc:
When the Image (test.php) is referenced by a html file (test.html) it is shown as broken in the browser window.

When calling test.php directly the Image is shown correctly, but by shift-reloading the page (test.php) the image is broken again (a normal reload shows the image).

It did not occur with php-4.0.5

Are you saying that the image works fine when it is
requested by itself (test.php), but not when it is
referenced by a html page (test.html)?
 [2001-07-23 09:20 UTC] andy@php.net 
I was not able to reproduce this error, and think that it is bogus
(or is a problem with his browser.)    Can anyone else verify
this?

The example script and html both work just fine for
me too. Try asking this on php-general@lists.php.net
as there are dozens of people who can help you with this.

Not a bug in PHP.

I have the very same bug, only using PHP 4.2.1 on a Linux machine!

I have absolutely no clue why this problem occours. My script:

show.php:
<?php
header("Content-type: image/jpeg");
$bild="/home/httpd/bilder/unkatalogisiert/".$bildname;
if ($fp=fopen($bild,"r")) {
  fpassthru($fp);
}
fclose($fp);
?>

When I refer to this image using e.g.:

<img src="show.php?bildname=blabla.jpg">

It appearently is loaded by the browser (takes a while) but then displayed as broken. Had this in Netscape 4.79 and IE 5.50. When I refer directly to the picture, i.e. I enter as an URL:

http://192.168.1.1/show.php?bildname=blabla.jpg

The picture loads perfectly. Strangely, when using the <img src> construct with Opera 6, it works! Something is quite messed up somewhere, I can find no solution whatsoever.
