I found my solution:

Instead of counter, I needed to name the foreach and add {$smarty.foreach.pr.iteration}. Worked great!

{foreach from=$orders item="order"}<img src="https://www.bunnyburybaby.com/u?CID=2412429&OID={$order.order.orderid}&TYPE=5000{foreach from=$order.products item=product name=pr}&ITEM{$smarty.foreach.pr.iteration}={$product.productcode}&AMT{$smarty.foreach.pr.iteration}={$product.price}&QTY{$smarty.foreach.pr.iteration}={$product.amount}{/foreach}&CURRENCY=USD&METHOD=IMG" height="1" width="20">{/foreach}

Thanks anyways folks!
