thecartpress product page image appears twice

You have 2 easy ways:

1- Hide weaver featured image in TheCartPress single product page:
.single-tcp_product span.featured-image {
display:none;
}
(you can paste it in TCP appaerance > Custom styles)

Or..
2- Duplicate page.php and call it as thecartpress.php, then open thecartpress.php and search and delete a span wiht the featured-image class.
