How to swap widget title for an image?

if you want to hard code it look for

function wp_widget_recent_entries($args) {}

in

wp-includes/widgets.php

Thanks. My knowledge is very basic, so how do I alter the following to put a jpeg in place of the title?

function widget_recent_entries($args) {
extract($args);
$title = __(‘Recent Posts’, ‘widgets’);
$r = new WP_Query(‘showposts=10’);
if ($r->have_posts()) :
?>
<?php echo $before_widget; ?>
<?php echo $before_title . $title . $after_title; ?>

<?php while ($r->have_posts()) : $r->the_post(); ?>
• “><?php if ( get_the_title() ) the_title(); else the_ID(); ?>

<?php endwhile; ?>

<?php echo $after_widget; ?>
<?php
endif;
}
