Slideshow/ IMG gallery not working

[Tim@DIM]

I am extremely new to all this.
i downloaded this slideshow template from the following URL: http://forum.leigeber.com/index.php?...ads&showfile=6

i added everything to my website and changed file names and link references accordingly. i ended up with the result of the attached img.



can someone help me figure out why the images are sticking out to the right instead of centering above the thumbnails like its supposed to?

heres my code:

/******IMG GALLERY*********/
<style type="text/css">
body {margin:0; background:#111; padding:5px; font:11px Verdana,Arial}
