I have tried your solution
$themepath = bloginfo('stylesheet_directory');
echo '<div class="bottomSlider"><img src="'.$themepath.'/images/sliderImg.jpg" /></div>';
and the ouput is
http://localhost/shriram/wp-content/themes/twentyeleven-child<div class="bottomSlider"><img src="/images/sliderImg.jpg"></div>
themepath is printing above the div not inside image tag....
help me on this .
