Problem with the Middleearth theme

I'm having a problem with images not displaying at the bottom of the page, even though the html code appears to be correct when I look at it, and everything else is normal. Is there something in the layout code of the theme I need to fix?

<p style="text-align: center;"><strong>Buttons - 88 x 31</strong></p>
<p style="text-align: center;"><img class="alignnone size-medium" src="http://dead-winters-night.uk/images/buttons/dwnbut63.gif" alt="" width="88" height="31" /> <img class="alignnone size-medium" src="http://dead-winters-night.uk/images/buttons/dwnbut64.gif" alt="" width="88" height="31" /> <img class="alignnone size-medium" src="http://dead-winters-night.uk/images/buttons/dwnbut65.gif" alt="" width="88" height="31" /> <img class="alignnone size-medium" src="http://dead-winters-night.uk/images/buttons/dwnbut66.gif" alt="" width="88" height="31" /> <img class="alignnone size-medium" src="http://dead-winters-night.uk/images/buttons/dwnbut67.gif" alt="" width="88" height="31" /></p>

Hi!

We have testes this code with the Middleearth theme, and all the pictures are displayed properly. Could you clarify the URLs of your website and pages where you have this issue?
