Hey!

1. Paste this to your theme / child theme functions.php:

if(!function_exists('avia_header_class_string'))
{
	function avia_header_class_string($necessary = array() , $prefix = "html_"){
		
		$no_lightbox = is_singular("product") ? "av-custom-lightbox" : "";

		if(empty($necessary)) $necessary = array(	'header_position', 
													'header_layout', 
													'header_size', 
													'header_sticky',
													'header_shrinking', 
													'header_topbar', 
													'header_transparency',
													'header_mobile_activation',
													'header_mobile_behavior',
													'header_searchicon',
													'layout_align_content',
													'header_unstick_top',
													'header_stretch',
													'header_style'
												);

		$settings  	= avia_header_setting();
		$class		= array();
		$post_id 	= function_exists('avia_get_the_id') ? avia_get_the_id() : get_the_ID();
		
		foreach($necessary as $class_name)
		{
			if(!empty($settings[$class_name]))
			{
				$result = array_filter(explode(' ', $settings[$class_name]));
				$class = array_merge($class, $result);
			}
		}
		
		if($post_id) $class[] = "entry_id_".$post_id;
		
		$class = apply_filters('avf_header_classes', $class, $necessary, $prefix);
		
		if(!empty($class))
		{
			$class = array_unique($class);
			$class = " ".$prefix.implode(" ".$prefix, $class);
		}

		
		return $no_lightbox.$class;
	}
}

2. Paste this to your theme / child theme functions.php:

function change_title_in_wc($args) {
	if(is_woocommerce()) $args['title'] = "Custom Title";
	return $args;
}
add_filter('avf_title_args', 'change_title_in_wc');

3. Use this plugin to change the WC image sizes:
