This plug-in can easily convert any colored image into a B&W greyscale image. It uses the the HTML5 canvas tag and a fallback for the old browsers


1 Include the plug into the page:

<script src="js/jQuery.BlackAndWhite.js"></script>

2 Set the image wrappers using the css:

.bwWrapper {

3 Initialize the plug in on window load (no $(document).ready()):

        hoverEffect : true, // default true
        // set the path to BnWWorker.js for a superfast implementation
        webworkerPath : false,
        // for the images with a fluid width and height 
        // to invert the hover effect
        invertHoverEffect: false,
        speed: { //this property could also be just speed: value for both fadeIn and fadeOut
            fadeIn: 200, // 200ms for fadeIn animations
            fadeOut: 800 // 800ms for fadeOut animations
