I got it to work using the code below, what happens is...it does not pass the size to the rest of the images.....The first image load in the flash player, the others are there but when you click to view them the flash player goes full screen. so the size variable is not being passed to flash...
{if $images ne ""}
{assign var="i_counter" value=1}
{section name=image loop=$images}
{if $images[image].avail eq "Y"}
{if $images[image].tmbn_url}
{if $i_counter eq 1}
<div class="shadowboxlinks"><a rel="shadowbox[images]" class="shadowbox" href="{$images[image].tmbn_url}" title="{$images[image].alt|escape}"><img src="{$ImagesDir}/zoom.gif" alt="{$lng.lbl_click_to_enlarge|escape}" /> {$images[image].alt|escape}{if $images[image].alt|escape eq ""}{$lng.lbl_image}{math equation="value+1" value=$smarty.section.image.index}{/if}</a></div>
{else}
<div class="shadowboxlinks"><a rel="shadowbox[images]" class="hidden" href="{$xcart_web_dir}/image.php?id={$images[image].imageid}&type=D" title="{$images[image].alt|escape}"><img src="{$ImagesDir}/zoom.gif" alt="{$lng.lbl_click_to_enlarge|escape}" /> {$images[image].alt|escape}{if $images[image].alt|escape eq ""}{$lng.lbl_image}{math equation="value+1" value=$smarty.section.image.index}{/if}</a></div>
