Found the offending {

now have to find where that additional css came from. No other site I manage has it so a little investigation is on the cards. It helped the shadowbox a little by surrounding the thumbnails with a border but I still can't get the left alignment working.
should I use the css, or call it directly from the shadowbox_images.tpl like
Code:
<div id="shadowbox_images"> to <div "float: left; width: 500px">
{if $images ne ""}
{section name=image loop=$images}
{if $images[image].avail eq "Y"}
{if $images[image].tmbn_url}
<div class="shadowboxlinks"><a rel="shadowbox[images]" href="{$images[image].tmbn_url}" title="{$images[image].alt|escape}"><img src="{$images[image].tmbn_url}" width=75 height=75/>{$images[image].alt|escape}{if $images[image].alt|escape eq ""}{/if}
</a></div>
{else}
<div class="shadowboxlinks"><a rel="shadowbox[images]" href="{$xcart_web_dir}/image.php?id={$images[image].imageid}&type=D" title="{$images[image].alt|escape}"><img src="{$images[image].tmbn_url}" width=75 height=75/>{$images[image].alt|escape}{if $images[image].alt|escape eq ""}{/if}</a></div>
{/if}
{/if}
{/section}
{/if}
</div>
Thanks again
