You can't animate the .src value directly with jQuery.
You will need to use two images, positioned on top of one another so one can be faded in on top of the other.
Both images should be preloaded or precached so there is no delay for an image to load after setting .src.
Working example: http://jsfiddle.net/jfriend00/n52Fr/
$(".container").hover(function() {
$(this).find(".fadeTop").fadeOut(1000);
}, function() {
$(this).find(".fadeTop").fadeIn(1000);
});
.container {
position: relative;
height: 100px;
width: 150px;
}
.container img {
position: absolute;
top: 0;
left: 0;
}
