I am not usually a Smarty guy, so I'm a bit stuck.

I want to echo the index of an array, but I want to increment it each time I echo it.

This is what I have...

<ul>
    {foreach from=$gallery key=index item=image}
    <li>
        <img src="{$image}" alt="" id="panel-{$index++}" />
    </li>
    {/foreach}
</ul>

It doesn't work.

Is the best way to do this to pre-process the array before handing it to Smarty?

Is there a way I can do this using Smarty?
