NextGen Problems with codes

Hi.

I get in my html-file a strange gray box before and after the image thumbnails.
The code come here:

<div class="entry clear">
<p><code>
</code>
</p>

And the also comes on several places in the html code eg for the page "testing-nextgen.htm"

I just want to get rid of these gray "boxes".

Thanx in advance!
