Условие smarty если фото 1шт то не выводить блок, если 2 и более

Товарищи подскажите пожалуйста как сделать правильно условие smarty 

мне надо выводить фото тогда когда их больше одного.

Если 1 фото добавлено но оно не отображается, если 2 и больше то блок отображается, звездочками показан сам блок

{if !empty($thumbnails)}
{footer_script}
  var error_icon = "{$ROOT_URL}{$themeconf.icon_dir}/errors_small.png"{if isset($maxRequests)}, max_requests = {$maxRequests}{/if};
{/footer_script}
{if $derivative_params->type == "thumb"}
{assign var=width value=520}
{assign var=height value=360}
{assign var=rwidth value=260}
{assign var=rheight value=180}
{else}
{assign var=width value=$derivative_params->sizing->ideal_size[0]}
{assign var=height value=$derivative_params->sizing->ideal_size[1]}
{assign var=rwidth value=$width}
{assign var=rheight value=$height}
{/if}
{define_derivative name='derivative_params' width=$width height=$height crop=true}
{assign var=idx value=0+$START_ID}
{foreach from=$thumbnails item=thumbnail}
{assign var=derivative value=$pwg->derivative($derivative_params, $thumbnail.src_image)}
{if !$derivative->is_cached()}
{combine_script id='jquery.ajaxmanager' path='themes/default/js/plugins/jquery.ajaxmanager.js' load='footer'}
{combine_script id='thumbnails.loader' path='themes/default/js/thumbnails.loader.js' require='jquery.ajaxmanager' load='footer'}
{/if}
{include file="grid_classes.tpl" width=$rwidth height=$rheight}
