Hi guys, I want to hover all the images and show the image with colour when mouseover (remove hover when mouseover). I hover it by using this line of code and it's work fine but I do not know how to add mouseover method to change fadeTo value become (400,1):

jQuery(window).load(function() {
    $('#grid div.thumb').fadeTo(400, 0.1);
            $('#grid div.thumb').each(function() {
                $(this).removeClass('no_overlay');
            }); 
});

this is my html:

<div id="grid" class="clearfix">
            <div class="thumb" id="1" data-project-categories="video">
                <a href="portfolio/video-and-slider.html" title="Video and Slider">
                    <img src="images/portfolio/341-384x263.jpg" alt="Video and Slider">

            </div>
    </div>

Any idea?

The jQuery extension that iamthwee provided looks pretty decent. If you were still wanting to see an example of how you could have coded this (or in this case, how I might have done it), here is a fiddle I have that should help http://jsfiddle.net/pixelsoul/WzrKW/
