Images in Woocommerce Product Sidebar [closed]

Open up that file (mini-cart.php) and edit line 40 where it contains

<?php echo $_product->get_image(); ?>

Change that to

<?php echo $_product->get_image( array( 150, 200 ) ); ?>

150 is the width and 200 is the height. Change it to whatever size you want.

After you have done that make sure to clear your cache and restart your browser as sometimes the mini cart gets cached.
