plugin Slashdigglicious drop shadows

I was able to find the drop shadow files here:
http://weblogtoolscollection.com/archives/2004/03/24/wordpress-javascript-quicktags/

and add this to your stylesheet:

/* slashdigglicious */
.slashdigglicious { margin-top: 1em; }
.slashdigglicious img {
	background: url(images/shadowAlpha.png) no-repeat right bottom;
	padding: 4px 10px 10px 4px;
	border: 0;
	border-top: #eee 1px solid;
	border-left: #eee 1px solid;
}
