Please Review my app - Css-Sprit.es

Hello HN,

I'd really love to have your feedback on this little tool I made. It can help you producing your CSS sprites for all your web developements needs.

Please add a "load image from URL" feature; don't make me upload my personal photos.

I uploaded a photo (bugs.jpg) and it showed up at the bottom of the screen, below the footer and outside the container! Firfox 3.5.2.

I am not exactly sure what it does; the only text that I thought would explain what it does only told me the generated code would be compatible with most browsers.

P.S. I like the giant buttons with the nice hover effect in the bottom; very tasteful.
