You could, if you grab this:
<div id="thumbhide">
<div id="thumbbox">
<div id="thumb_container">
<div id="thumbgall">
<div id="thumbs">
<div id="widthbox"><?php getthumbnailimages($gallerypath, 'tempgallery', $thumbpath); ?></div>
</div>
</div>
</div>
<div id="back">
<script type="text/javascript">if(thumbnailnum>maxthumbvisible){document.write("<div id='leftmore'><ul><li><a href=\"javascript:checkbutton(addposition('minus'));movethumbs('plus');\"><img src='rsrc/buttonblank.gif' width='15' height='115' border='0' /></a></li></ul></div>");}</script>
</div>
<div id="more">
<script type="text/javascript">if(thumbnailnum>maxthumbvisible){document.write("<div id='rightmore'><ul><li><a href=\"javascript:checkbutton(addposition('plus'));movethumbs('minus');\"><img src='rsrc/buttonblank.gif' width='15' height='115' border='0' /></a></li></ul></div>");}</script>
</div>
</div>
</div>
and place it where you want this would take the thumbnails out of it's current position, I don't know what it would do, I haven't tested it. You might need to modify the button that hides and shows the thumbnails, but that will get you started. Hope it works like you want it too.
