how to make an image grow and make everything else dark until you click close

Anyone know an easy way to do this? I have some web links in my app
with pictures, and I'd like to implement that effect that I've seen a
lot where when the user clicks on the image, it sort of grows and the
rest of the page becomes dark until the user clicks close (or clicks
the picture). Is there an easy rails plugin for this?


Hey Dino -

Thanks, works great!
