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 *required*
imageHeight: '133px',                         //height of tab image *required*
imageWidth: '44px',                           //width of tab image *required*
});
