Wordpress show posts that start today and end in one year

I would like to know some way to do this, maybe someone ca开发者_StackOverflow社区n help me out a little bit! This is the code i have at the moment:

<?php $featured = new WP_Query('showposts=10&cat=23'); while($featured ->have_posts()) : $featured->the_post();  ?>
<?php if (  (function_exists('has_post_thumbnail')) && (has_post_thumbnail())  ) { ?>
<?php $image_id = get_post_thumbnail_id();  $image_url = wp_get_attachment_image_src($image_id,'large');  $image_url = $image_url[0]; ?>
<?php $blogurl = get_bloginfo('url'); $image_url = str_replace($blogurl, '', $image_url); ?>

So straight forward question is how can i display posts that start today and end in one year, from a specific category Thanks!

See the Time Parameters section in the WordPress Codex page for WP Query, the part about filters should prove useful. Alternatively, see this post on how to hide content based on age of post in WordPress.
