Archive problem – getting archive to display all posts

I am having difficulty getting my archives on my photoblog to display properly. For the Month Archives, I would like it to display all posts in a month. For the category archives, I would like it to display all posts in the category at once. However for both it will only display the ten most recent posts. How can I get the archives to display all posts for a category and month?

The archives in question are to be found here…

Here is the code in my archive.php template file:

<?php get_header(); ?>

<!-- BEGIN main -->
<div id="main"><div id="main-inner">

<?php if (have_posts()) : ?>

<?php $post = $posts[0]; // Hack. Set $post so that the_date() works. ?>
<?php /* If this is a category archive */ if (is_category()) { ?>
<h2 class="page-title">Archive for the '<?php echo single_cat_title(); ?>' category</h2>
<?php /* If this is a monthly archive */ } elseif (is_month()) { ?>
<h2 class="page-title">Archive for the month '<?php the_time('F, Y'); ?>'</h2>

<?php /* If this is an author archive */ } elseif (is_author()) { ?>
<h2 class="page-title">Author Archive</h2>

<?php /* If this is a paged archive */ } elseif (isset($_GET['paged']) && !empty($_GET['paged'])) { ?>
<h2 class="page-title">Blog Archives</h2>

<?php } ?>

<?php while (have_posts()) : the_post(); ?>
<!-- BEGIN post -->
<div id="post-<?php the_ID(); ?>" class="post clearfix">
<div class="post-body">
<a href="<?php the_permalink(); ?>" title="Permanent Link to '<?php the_title(); ?>'"><?php the_excerpt(); ?></a>
</div>
<h3 class="post-title"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to '<?php the_title(); ?>'"><?php the_title(); ?></a></h3>
<h4 class="post-meta"><?php the_time('F jS, Y') ?></h4>
</div>
<!-- END post -->
<?php endwhile; ?>

<?php else : ?>

<h3>Not Found</h3>

<?php endif; ?>

</div></div>
<!-- END #main -->

<?php get_sidebar(); ?>

<?php get_footer(); ?>

And here is the code for my page-archives.php file:

<?php
/*
Template Name: Archives Template
*/
?>

<?php get_header(); ?>

<!-- BEGIN main -->
<div id="main"><div id="main-inner">

<h2 class="page-title">Archives</h2>

<h3 class="post-title">Recent photos</h3>
<?php
$posts = get_posts('numberposts=30');
foreach($posts as $post) :
setup_postdata($post);
?>
<!-- BEGIN post -->
<div id="post-<?php the_ID(); ?>" class="post clearfix">
<div class="post-body">
<a href="<?php the_permalink(); ?>" title=""><?php the_excerpt(); ?></a>
</div>
<h3 class="post-title"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to '<?php the_title(); ?>'"><?php the_title(); ?></a></h3>
<h4 class="post-meta"><?php the_time('F jS, Y') ?></h4>
</div>
<!-- END post -->
<?php endforeach; ?>

</div></div>
<!-- END #main -->

<?php get_sidebar(); ?>

<?php get_footer(); ?>

Help is appreciated. Thank you.
