Yeah it does work in 4.1.9...
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"}
{include file="thickbox/thickbox_productpage.tpl" }
{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"}
{include file="thickbox/thickbox_productpage.tpl" }
{/if}
</div>
{if $product.fulldescr ne ""}{$product.fulldescr}{else}{$product.descr}{/if}
{if $active_modules.Magnifier ne "" && $config.Magnifier.magnifier_image_popup eq 'Y' && $zoomer_images ne '' && $js_enabled eq 'Y'}
{include file="modules/Magnifier/popup_magnifier.tpl"}
{/if}
Look in your /skin1/customer/main/product.tpl and look for this code( it will be close to the top...it should resemble something like this once you put the {include file="thickbox/thickbox_productpage.tpl" }...for some reason I have to put it in both IF statements for it to show all my detailed images....don't know why but for some product it uses one and for others it uses the other...so I put it in both and it works fine...but I do want to work on this a bit more to find out why...because the first IF statement is really where it goes...also in the thickbox.tpl...I had to put {literal} tags around the js callout as w/o them the animated gif was always showing on top....
