This effect is very strange, when an ordinary image is added to glossy.js, it will become the effect after professional PS design, just look at the image ~~~~~~~~~~~
Glossy.js 1.2 allows you to add corners and shading and shadow to images on your webpages (alternatively: corner.js). It uses unobtrusive javascript to keep your code clean.
It works in all the major browsers - Mozilla Firefox 1.5+, Opera 9+, IE6+ and Safari. On older browsers, it’ll degrade and your visitors won’t notice a thing.
