How to tile an image in the Sidebar

I’m sure I’m missing something basic, but I’ve been googling all over and trying to copy instructions as best as I can and can’t get it right.

I want to have an image tiled down my sidebar
image – https://hockeyphotography.com/testblog/wp-content/themes/journalist/images/sidebartile.gif

on https://hockeyphotography.com/testblog

I not only haven’t gotten the image to appear at all, but the footer has now moved into the sidebar position. Ugh.

I’ll put the sidebar.php code first since it is much shorter than the stylesheet (originally I had the background code here, but it appeared as text so I just wiped everything I wasn’t using out:

<div id="sidebar">
<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar() ) : ?>

<?php endif; ?>

<?php if (function_exists('wp_theme_switcher')) { ?>
<h3>Themes</h3>
<div class="themes">
<?php wp_theme_switcher(); ?>
</div>
<?php } ?>

</div>

and the stylesheet code:
