Sidebar image not showing up

I am new to css and am having a problem with my bottom sidebar image not showing up… My site is https://www.moneytalks-bswalks.com and the referenced sidebar.php code (within the “boredom” template) is:

• <div class=”sb_header”><h2><?php _e(‘Other Info’); ?></h2> </div>

<div align=center>

<div id=”sidebar_bottom”>

</div>

Its the display of the “sidebar_bottom” image that is the problem… Any help would be greatly appreciated… Thank you.
