Order Category Posts

I’d like to order all the posts listed on my category.php page alphabetically.

Here is the code on my category.php page:

<?php
/**
 * The template for displaying Category Archive pages.
 */

get_header(); ?>
<?php global $q_config; ?>

			<div id="product_gallery" role="main">

			<?php while ( have_posts() ) : the_post(); ?>

 			 <?php 	//This checks what language qTranslate has selected and returns the appropriate ShortDesc
					if (ppqtrans_getLanguage() =="en") {
					   $key = "byline_en";
					   $description = get_post_meta($post->ID, $key, true);
					}
					if (ppqtrans_getLanguage() =="fr") {
					   $key = "byline_fr";
					   $description = get_post_meta($post->ID, $key, true);
					}
				?>

			<div class="product_thumbnail">
			<a href="<?php the_permalink() ?>">
			<?php //the_post_thumbnail grabs the post's "featured image" this feature has added theme support in the child theme functions.php ?>
			<?php the_post_thumbnail('thumbnail', array('class' => 'thumbnail')); ?>
			</a>

			<?php //This piece of code figures out the corrosponding post_title of the featured image ?>
			<h1 class="post_caption"><?php the_title(); ?></h1>
			<p><?php echo $description; ?></p>
			</div> <!-- product_thumbnail -->

			<?php endwhile; // end of the loop. ?>

			<div class="clear"></div>

</div><!-- #content -->

<?php get_footer(); ?>

What do you think the best way to go about that would be?
