If author display image (Archive Page)

Hi there,

I was wonder how to display a image at the top of archive page for each author.

for example;
if_author(‘1’)
Display image example.jpeg

Here is what I have;

<?php get_header(); ?>
<?php global $data;?>
<div id="blocks-wrapper" class="clearfix">
	<div id="blocks-left" class="eleven columns clearfix">
 			<!--Archive content-->
		<!-- .blogposts-wrapper-->

 					 		<h2 class="blogpost-wrapper-title" style="margin-top:30px;">
 							<?php if(is_day()): ?>
 								<?php printf(__('Daily Archives: %s', 'bresponZive'), get_the_date()); ?>
 							<?php elseif(is_month()) : ?>
 								<?php printf(__('Monthly Archives: %s', 'bresponZive'), get_the_date('F Y')); ?>
 							<?php elseif(is_year()) : ?>
 								<?php printf(__('Yearly Archives: %s', 'bresponZive'), get_the_date('Y')); ?>
 							<?php elseif(is_category() || is_tag()): ?>
 								<?php printf(__('Articles Posted in the " %s " Category', 'bresponZive'), single_cat_title('', false)); ?>
 							<?php elseif(is_author()):
							$curauth = (isset($_GET['author_name'])) ? get_user_by('slug', $author_name) : get_userdata(intval($author));
							?>
 								<?php printf(__('Articles Posted by the Author: %s', 'bresponZive'), $curauth->nickname);  

								?>
 							<?php else: ?>
 								<?php _e('Blog Archives', 'bresponZive'); ?>
 							<?php endif; ?>
  						</h2>
						<?php include_once('includes/blog_loop.php');?>

 	</div>
 			<!-- END MAIN -->
 <?php get_sidebar(); ?>
 <?php get_footer(); ?>

What code and where do I place it?
