I can get the layout to display all Exchange products using this query in the extension functions.php file:
<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts("it_exchange_category&tag_ID=7&post_type=it_exchange_prod&paged=$paged"); ?>
I have tried different combinations of the query but keep hitting a brick wall. Also, the product image is not appearing.
