jQuery Plugin: Sideswap v 1.0.3
Author: BrianBlocker.com
Tools: Dreamweaver CS4 / 2009 iMac (early edition) / 2009 Mac Mini (late edition)
modified by mike howard 20100512 to make it grab selected tags (defaults to img) and strip any other html
also added ability to pass a list of images so they load a little later
added detection of msie for pngs - ie can't transition transparent pngs so the transition speed is set to 0 20100705
fixed msie pngs where the faded element may not have been an image 2010831
modified the png transparency issue to a setting so you can still have fading non transparent pngs mh 20110429

example usage:
jQuery(document).ready(function() {
	jQuery('#block-block-25').sideswap({selector:'a'});
});

'#block-block-25' is id of the containing element
{selector:'a'} selects elements that can get faded within the containing element
