Blocklayered: pattern images not displayed properly

[getdatakick]

Theme override incorrectly constructs background url img/co/{$id_value}.jpg instead of /img/co/{$id_value}.jpg

code location:

niara/modules/blocklayered/blocklayered.tpl

Lines 73 to 80 in 01412c6

	id="layered_id_attribute_group_{$id_value}"
	aria-label="{$value.name|escape:'html':'UTF-8'}"
	{if !$value.nbr}disabled="disabled"{/if}
	style="background: {if isset($value.color)}{if file_exists($smarty.const._PS_ROOT_DIR_|cat:"/img/co/$id_value.jpg")}url(img/co/{$id_value}.jpg){else}{$value.color}{/if}{else}#CCC{/if};">
	{if isset($value.checked) && $value.checked}<input
	type="hidden"
	name="layered_{$filter.type_lite}_{$id_value}"
	value="{$id_value}">{/if}

Also, template expects .jpg files. This might not be the case anymore
