Another very cool effect – which is very popular among clients – is indeed the fade in/fade out on mouseover. The code below set opacity to 100% on hover, and to 60% on mouseout.
$(document).ready(function(){
$(".thumbs img").fadeTo("slow", 0.6); // This sets the opacity of the thumbs to fade down to 60% when the page loads
$(".thumbs img").hover(function(){
$(this).fadeTo("slow", 1.0); // This should set the opacity to 100% on hover
},function(){
$(this).fadeTo("slow", 0.6); // This should set the opacity back to 60% on mouseout
});
});
