Allow images to blend in with your background until a mouseOver event occurs...

Copy and Paste this into your head tags:
<script> nereidFadeObjects = new Object(); nereidFadeTimers = new Object(); /* object - image to be faded (actual object, not name); * destop - destination transparency level (ie 80, for mostly solid) * rate - time in milliseconds between trasparency changes (best under 100) * delta - amount of change each time (ie 5, for 5% change in transparency) */ function nereidFade(object, destOp, rate, delta){ if (!document.all) return if (object != "[object]"){ //do this so I can take a string too setTimeout("nereidFade("+object+","+destOp+","+rate+","+delta+")",0); return; } clearTimeout(nereidFadeTimers[object.sourceIndex]); diff = destOp-object.filters.alpha.opacity; direction = 1; if (object.filters.alpha.opacity > destOp){ direction = -1; } delta=Math.min(direction*diff,delta); object.filters.alpha.opacity+=direction*delta; if (object.filters.alpha.opacity != destOp){ nereidFadeObjects[object.sourceIndex]=object; nereidFadeTimers[object.sourceIndex]=setTimeout("nereidFade(nereidFadeObjects["+object.sourceIndex+"],"+destOp+","+rate+","+delta+")",rate); } } </script>

Insert this code into the img tag (ie. in <img src="image.jpg">)

style="filter:alpha(opacity=25)" onmouseover="nereidFade(this,100,30,5)" onmouseout="nereidFade(this,25,50,5)"
