Pulling alt text from wordpress images

i'm trying to pull the alt text from an image array to use elsewhere but i'm getting nowhere..

here's the code:

        global $post;
        $args = array( 'numberposts' => 12, 'post_type' => 'clientes', 'orderby' => 'ASC');
        $myposts = get_posts( $args );
        $alt_text = get_post_meta($args , '_wp_attachment_image_alt', true);
        foreach( $myposts as $post ) :  setup_postdata($post); 

        ?>
        <li>
            <!--BEGIN .hentry -->
            <div class="post_box">
                <div class="post-thumb left gallery">
                    <a href="<?php the_permalink() ?>">
                        <?php the_post_thumbnail('full'); ?>
                        <div class="overlay"><img src="<?php echo $alt_text; ?>.jpg" /></div>
                    </a>

                </div>    
            <!--END .hentry-->  
            </div>

I'm pretty certain that my fault is with this line:

            $alt_text = get_post_meta($args , '_wp_attachment_image_alt', true);

but I lack the knowledge to fix it...

thanks

You are misusing get_post_meta: the first argument should be the post identifier not an array of args.

you need to call get_post_meta inside the foreach loop to pull each post's unique data:

foreach( $myposts as $post ) :
$alt_text = get_post_meta($post->ID , '_wp_attachment_image_alt', true);
endforeach;
