Firefox -moz-border-radius won't crop out image?

Workaround: Set the image as the background of a container element, then add border radius on that element.

Does it not crop if you apply the border radius directly to the img element? There are known issues with -moz-border-radius as far as contained content is concerned.

--edit

OK, it doesn't crop img either. If your image is some sort of png/gif on a solid background you may be able to do something like this:

img {
    border: 10px solid white;
    -moz-border-radius: 10px;
}

But if you're trying to get rounded corners on a photo then it's not going to work in 3.5.

I think to have the answer but sorry for my english... I resolved the question putting another div with border and no background color over the image.

#imageContainer {
  -webkit-border-radius:10px
  -moz-border-radius:10px;
  z-index:1;
}
#borderContainer {
  position:absolute;
  border:1px solid #FFFFFF;
  -webkit-border-radius:10px
  -moz-border-radius:10px;
   z-index:10;
}
