Hello, this CODE ist running well:

add_action('init','ava_product_sidebar_init_mod', 50);
function ava_product_sidebar_init_mod() {
	remove_action( 'woocommerce_before_single_product_summary',  'avia_close_image_div', 20);
	add_action( 'woocommerce_before_single_product_summary',  'avia_close_image_div_mod', 20);
	add_action( 'woocommerce_after_single_product_summary', 'avia_add_sidebar_mod', 19);
}

function avia_close_image_div_mod() {
	echo "</div>";
}

function avia_add_sidebar_mod() {
	global $product, $avia_config;
	if( is_product() ) {
		$avia_config['currently_viewing'] = "shop_single";
		get_sidebar();
	}
}

connect it with this css

.single-product-main-image {
    width: 25%;
}

.single-product-summary {
    overflow: hidden;
    width: 45%;
    float: left;
    margin-right: 5%;
}

.single-product .sidebar {
    width: 25%;
}

its a earlier solution from Kriesi

But what code is for the right side? Can you please answer this?
