Hi!
We are not quote sure what size are you talking about? The Most Wanted widget? The images are small by default. There is, in woocommerce.css on line 2747
.woocommerce ul.cart_list li img, .woocommerce ul.product_list_widget li img, .woocommerce-page ul.cart_list li img, .woocommerce-page ul.product_list_widget li img {
width: 40px;
height: auto;
position: absolute;
top: 6px;
left: 0;
}
The width of the image is controlled here. The original is 90x90px. If you increase it to 90px, you’ll also have to modify on line 2732 in woocommerce.css
.woocommerce ul.cart_list li, .woocommerce ul.product_list_widget li, .woocommerce-page ul.cart_list li, .woocommerce-page ul.product_list_widget li {
padding-left: 110px;
}
For everything to look ok.
