Display image alt text within a div on page

Display image alt text within a div on page

I have an image displaying as a background on my page through a plugin,
and I'm trying to display the ALT text from that image within a DIV
elsewhere on the page.
Here's the code that's coming up:
<!-- Background Manager Start -->
<div id="myatu_bgm_img_group" class="myatu_bgm_fs" style="overflow:
hidden;"><script type="text/javascript">
/*<![CDATA[*/
try{(function(a){myatu_bgm.addTopImage("",function(){if((typeof
myatu_bgm!=="undefined")&&(myatu_bgm.initial_ease_in==="true")){a(this).fadeIn("slow")}else{a(this).show()}})}(jQuery))}catch(e){};
/*]]>*/
</script><noscript><img id="myatu_bgm_top" class="myatu_bgm_fs"
src="http://mgrezova.webfactional.com/wp-content/uploads/2013/06/agnesbshirt.jpg"
alt="Caption Text" /></noscript></div>
<!-- Background Manager End -->
Can someone suggest javascript, or something else, that would allow me to
output that "Caption Text" within the following DIV?
<DIV class="quote">
<DIV class="inner-quote">
</DIV>
</DIV>
Any help is hugely appreciated.
