Erm, what about your transparent pixel? We need it to see why it makes your corner disappear. Honestly though, I have no idea what you need it for.
And you'll need to change the extension of the image file in your code, too.
While we're at it, why do use one single line of CSS in the HTML document, when you could just stuff it in the CSS file (style1.css) you're linking to? In fact, try switching everything to CSS altogether, that will make your code much easier to read. And maybe post it for us to see, too.
