I can't figure out how to select this element

I can't figure out how to select this element

Hi,

I am trying to change an attribute of an element but can't figure out what the selector is to select it.

the page code is like this

<div class="slideshow" id="slideshow"><span class="image-wrapper current" style="opacity: 1;"><a title="" href="#2" rel="history" class="advance-link">&nbsp;<img alt="" src="images/samples/1.jpg"></a></span></div>

I want to add a top css attribute to the img tag. Please help me out

I tried many things such as
$('.advance-link:first')
$('.advance-link:firstChild')

but none seem to be working. The img gets generated by another script so I can't add an id or class to it. I figured an expert at selectors would be able to explain how to select it.

Thanks!
