There's a link to it at the bottom of your forum here.
Run the Gallery Light through the Validator, if you're bored some day. All of the IMG tags in the template are missing the ALT parameter, and the table formatting is incorrectly nested somewhere. I'm about half surprised that it doesn't fall all over itself.
I found the table problem:
//Check which BBCode parser exists parse_bbc for 1.1 or doUBBC for 1.0.x
$parse_exist = function_exists('parse_bbc');
echo '<table cellspacing="0" cellpadding="10" border="0" align="center" width="90%" class="tborder">
<tr class="titlebg">
<td colspan="2">' . $txt['gallery_text_galleryname'] . '</td>
<td>' . $txt['gallery_text_gallerydescription'] .'</td>
<td>' . $txt['gallery_text_totalimages'] . '</td>
';
if($g_manage)
echo '
<td>' . $txt['gallery_text_reorder'] . '</td>
<td>' . $txt['gallery_text_options'] . '</td></tr>';
That last part should have been
<td>' . $txt['gallery_text_options'] . '</td>';
echo '
</tr>';
or else non-admins will never get the end of the table row.
