[Plugin: WP AD Gallery] Getting duplicate slider. Why?

This is not duplacate, you must have thumbs but size is problem…
II had the same problem, and i modify the code.
In the file wp-ad-gallery/shortcode/shortcode.php
at the end, you will find that :

$image_src = "<a href='$img_src[0]'><img src='$img_src[0]' title='$img_title' alt='$img_alt' height='100' class='image-$id'>";

		$output .= "
<li>";
		$output .= "$image_src";
		$output .= "</li>
</a>
		";
	}

	$output .= "		<!-- .ad-thumb-list -->
			</div><!-- .ad-thumb -->
		</div><!-- .ad-nav -->
		</div><!-- .image-wrapper-container' -->\n";

	return $output;
}

?>

I changed that :
$image_src = "<a href='$img_src[0]'><img src='$img_src[0]' title='$img_title' alt='$img_alt' height='100px' width='100px' class='image-$id'>";
Maybe it’s not a good solution but it’s working for me.
Sorry for my bad english…
