Fix: show original image on product page if size < thumbnail size

General General Questions

I just made a modification (4.0.1) which I want to share: No resize of Product-Details-Page image/thumbnail if the original image width/height is < Thumbnail width/height.



Problem of cscart: If “Product details page thumbnail height/width” is set to 250 for example, it will auto-resize a width:100 product-image to 250, making it to look blur of course.



Solution:



create: hooks/products/image_wrap.override.tpl:


{if !$no_images}<br />
<br />
	<div class="image-border center cm-reload-{$product.product_id}" id="product_images_{$product.product_id}_update"><br />
<br />
	{if $product.list_discount_prc}<br />
		<span class="thumb-discount-label"><br />
			{strip}<br />
			{__("save_discount")} {$product.list_discount_prc}%<br />
			{/strip}<br />
		</span><br />
	{/if}<br />
<br />
	{* custom *}<br />
	{$my_image_data=$product.main_pair|fn_image_to_display}<br />
	{if $my_image_data.width < $settings.Thumbnails.product_details_thumbnail_width && $my_image_data.height < $settings.Thumbnails.product_details_thumbnail_height}<br />
		{* original size *}<br />
		{include file="views/products/components/product_images.tpl" product=$product show_detailed_link="Y"}<br />
	{else}<br />
		{* thumbnail size *}<br />
		{include file="views/products/components/product_images.tpl" product=$product show_detailed_link="Y" image_width=$settings.Thumbnails.product_details_thumbnail_width image_height=$settings.Thumbnails.product_details_thumbnail_height}<br />
	{/if}<br />
	{* /custom *}<br />
<br />
{/if}
