nextgen image gallery gap problem

hello all, thanks for taking the time to read my problem…

i am not a great coder by any means at all so i am very perplexed about this, let me break it down.

i have used both wp media gallery and am now using nextgen plugin for my media gallery – both have presented the same problem with my current theme, if i switch my theme, the problem goes away.

i have added adsense codes into my left and right sidebars in my sidebar.php and i see a huge gap after the first set of images…here is my sidebar.php code

<div id=”subnav”>

<?php if ( !function_exists(‘dynamic_sidebar’) || !dynamic_sidebar(“Left Sidebar”) ) : ?>

<?php echo show_ad_camp_1(); ?>

<?php endif; ?>

</div>

<div id=”extras”>

<?php if ( !function_exists(‘dynamic_sidebar’) || !dynamic_sidebar(“Right Sidebar”) ) : ?>

<?php echo show_ad_camp_2(); ?>

<?php endif; ?>

</div>

if i completely clear out my sidebar.php file i do not see the gap in the image gallery at all. if i change my theme i do not see the image gap at all. i only see the gap when i have this code in my sidebar.php file…

help!

thank you so much in advance, i really do appreciate it as i am going crazy….

thanks!
