How to call Main Image

[coca cola]

We use Toolkit to call a quicklist of products (newest, featured, best selling etc.) The code calls for a thumbnail image which we no longer use. All our images are now main.

<mvt:if expr="NOT ISNULL l.settings:sub_product:thumbnail">
<a target="_blank" href="&mvt:global:sessionurl;Screen=PROD&Product_C ode=&mvta:sub_product:code;&Store_Code=&mvta:store :code;" rel="nofollow">
<img src="http://&mvta:global:domain:name;/Merchant5/&mvt:sub_product:thumbnail;" border="0"></a> </mvt:if>

I've tried replacing the &mvt:sub_product:thumbnail; with main, imageroot, and fullsize to no avail.

Then I found this code using another toolkit function but it doesn't work either:
<mvt:item name="toolkit" param="customimage|big|l.all_settings:item:product _id|fullsize" />
<mvt:if expr="g.big">
<img src="&mvt:global:imageroot;&mvte:global:big;">
</mvt:if>

Anyone found a way to fix this?

I also tried without success:

<mvt:item name="toolkit" param="customimage|big|l.all_settings:sub_products |fullsize" />
