title: CSS background-image : url("...") properties have also ALT?
body: <p>I am inserting images in TD's in a table with</p>
  
  <p><code>style="background-image: url("my_url_goes_here")</code></p>
  
  <p>Then I apply a transparent PNG mask in that TD so that it rounds the image corners
  (same colour as background corners, and it shows the middle of the picture)</p>
  
  <p>I wonder if i can write the ALT of the image in the CSS part (<code>style = "background-image: url()</code>) as if I am to write the ALT to the mask image (which is what users can save if they right click on the image), Google will index transparent masks with ALT from the  image.</p>
  
  <p>If it's not clear what I'm asking, I will explain further, just ask.</p>
  
  <p>Also, a friend of mine told me just minutes ago over the phone that css3-round borders can be applied to all sorts of things, not just borders, but also images etc. It'd be lovely if this is the case, i'm not sure round borders will round images too, never tried it tho' (exception as usual IE, where they show square).</p>
  
  <p>Thanks.</p>
