First menu item image not showing

I finally found the answer to this! The problem was only on the wpsc-single_product.php page. I had to delete these lines from the theme.functions.php file in wpsc-includes folder.

function wpsc_the_featured_image_fix($stuff){
	global $wp_query;
	remove_action('post_thumbnail_html','wpsc_the_featured_image_fix');
	if(isset($wp_query->query_vars['wpsc-product'])){
		$stuff ='';	?>
		<img src="<?php header_image(); ?>" width="<?php echo HEADER_IMAGE_WIDTH; ?>" height="<?php echo HEADER_IMAGE_HEIGHT; ?>" alt="" /><?php
	}
	return $stuff;

}

add_action('post_thumbnail_html','wpsc_the_featured_image_fix');
