Absolute links invalid with forms

Anon

My site (www.snapherup.com) is written entirely in PHP and I have set up a banner-rotation system. The banner info is pulled from a random row in a MySQL database which includes the HREF and IMG SRC data to insert into the HTML. The SRC links are absolute http://... references as they go to a third-party affiliate network.

This all works fine when browsing around the site. However, whenever a form is submitted, the resulting page does not show the images (just the little red cross in IE). Why should going to a page by submitting a form be any different from going to a page by clicking on a link? Is it something to do with data posted in the header???

You can see the problem for yourself by going to the homepage at www.snapherup.com and clicking on the "Log in" button on the right (even without entering a username/password).

N.B. The exception to this is if you see an Amazon banner appear as I store these locally.

Thanks for any help.

No, there should be another problem, the form has nothing to do with the images.
Could you send the code?

OK, I've set up a very simple page that replicates the behaviour. All it consists of is a basic form and an absolute path to a banner image. When you first load the page, the banner appears. When you submit the form (which routes to the same page), the banner does not display.

You can test the page yourself at http://www.jonrobins.co.uk/test.php

The source code is as follows:

<body>
<a href="http://www.affiliatewindow.com/cgi-bin-local/a.pl?p0000005&6578" target="_blank"><img src="http://www.awin1.com/u/p0000005/showban.asp?id=6578&img=PBox480x60button.jpg" width="468" height="60" border="0" align="middle"></a>
<br><br>
<form name="theform" method="post" action="test.php">
Test field
<br>
<input type="text" name="testfield" value="" size="25" maxlength="31">
<input type="submit">
<input type="hidden" name="submit" value="true">
</form>
</body>

By the way, I realise this is no longer really a true PHP question, as I have stripped all the PHP out of the source code to replicate the behaviour and it still occurs with just HTML. But I'd still be glad of any help!

I've checked the test link and it works just fine.

Well, the link always works. But what about the image? Did you see the banner image after you had submitted the form? That's where the problem lies.
