Oops...looks like the new forum corrupted the code. the [img] tags shouldn't be there. Replace this:
<img src="{$images[image].tmbn_url}">
with this:
{***----ORIGINAL CODE-------
<img src="{$images[image].tmbn_url}">
--------ORIGINAL CODE***}
{***--Startwithsecondimage---***}
{if $images[image].tmbn_url ne $images[0].tmbn_url }
<img src="{$images[image].tmbn_url}">
{/if}
{***--Startwithsecondimage---***}
