[TelaFirma]

This is one of the things that has changed over the last few releases... sorry missed this one. I have updated my instructions. Thanks for catching this. The section should read now...

Find the code:

{if $active_modules.Detailed_Product_Images ne "" && $config.Detailed_Product_Images.det_image_popup eq 'Y' && $images ne '' && $js_enabled eq 'Y'}
{include file="modules/Detailed_Product_Images/popup_image.tpl"}
{elseif $product.force_image_type eq 'W' && $product.variantid}
{include file="product_thumbnail.tpl" productid=$product.variantid image_x=$product.image_x image_y=$product.image_y product=$product.product tmbn_url=$product.tmbn_url id="product_thumbnail" type="W"} 
{else}
{include file="product_thumbnail.tpl" productid=$product.productid image_x=$product.image_x image_y=$product.image_y product=$product.product tmbn_url=$product.tmbn_url id="product_thumbnail" type="P"} 
{/if}

and replace it with

{** Dynamic Images - Tela Firma **}
{if $active_modules.Dynamic_Images}
{include file="modules/Dynamic_Images/product_image.tpl}
{else}

{if $active_modules.Detailed_Product_Images ne "" && $config.Detailed_Product_Images.det_image_popup eq 'Y' && $images ne '' && $js_enabled eq 'Y'}
{include file="modules/Detailed_Product_Images/popup_image.tpl"}
{elseif $product.force_image_type eq 'W' && $product.variantid}
{include file="product_thumbnail.tpl" productid=$product.variantid image_x=$product.image_x image_y=$product.image_y product=$product.product tmbn_url=$product.tmbn_url id="product_thumbnail" type="W"} 
{else}
{include file="product_thumbnail.tpl" productid=$product.productid image_x=$product.image_x image_y=$product.image_y product=$product.product tmbn_url=$product.tmbn_url id="product_thumbnail" type="P"} 
{/if}

{/if}
{** /Dynamic Images - Tela Firma **}

sorry for the confusion.
