You're looking to customize template.html. This is where you can
remove the padding from arround the images and remove the navagation
from the screen. See readme.txt for a list of All Template tags. To
unlink the main image find this around line 374 of phpslideshow.php
$images = "<a href='$path?directory=$path_to_images
$auto_url¤tPic=$next'>";
$images .= "<img src='$path_to_images/$item[0]' class='image'
alt='$lang_img_alt' title='$lang_img_hover'></a>";
and change it to
$images = "<img src='$path_to_images/$item[0]' class='image'
alt='$lang_img_alt' title='$lang_img_hover'>";
