Button Background...

I followed the tutorial for the metallic blue button used on pank pages. My button looks great however How am I gonna use just the button for my website?? the whole image is still there and if i cut it i loose the drop shadow effect. If I delete background and just have button I save image as gif with transparancy it still looks dumb

Link: This is how button looks atm:

i can't see that link, but why not keep the background and the shadow and save it as a jpeg?

There is updated link

It would be possible by my button background is white and the website background is black as well :/
