Here is a set of 131 Photoshop Layer Styles created by DezinerFolio in .ASL (Photoshop Layer Style) format.
This set of layer styles could be the fastest way to create Web 2.0 elements like buttons, headers, content backgrounds and a lot other stuff... I have been using these styles for a number of years now and they are incredibly handy to have.
