Images not showing in Topics

Hi, I have a pretty much default new installation of 2.50 but for some reason if I edit a topic and add an image it just doesnt appear.

Looking at the source of the rendered page its like:

<div class="topicpage-body">
        <p>Put your "About Us" information here. You can edit this in the admin site.</p>
<p><img src="http://localhost:2640/Content/Images/uploaded/HomePage/some-image.png" width="0" height="0" /></p>
    </div>

That image path is fine and valid but no image appears. This applies to all topic pages, text renders fine but no images. Checked CSS for topicpage-body but nothing weird there and the CSS is pretty much stock as its a new install.

Anyone any ideas?

Thanks.

Ha Ha, ignore, just seen the width and height values :)
