tabSlideOUt v1.3
    
By William Paoli: http://wpaoli.building58.com

To use you must have an image ready to go as your tab
Make sure to pass in at minimum the path to the image and its dimensions:
    
example:
    
$('.slide-out-div').tabSlideOut({
tabHandle: '.handle',                         //class of the element that will be your tab -doesnt have to be an anchor
pathToTabImage: 'images/contact_tab.gif',     //relative path to the image for the tab
imageHeight: '133px',                         //height of tab image
imageWidth: '44px',                           //width of tab image   
});

or you can leave out these options
and set the image properties using css
