How can I make the shiny glow effect around an icon/image? (Pics provided inside)

Question

Before mouse over:

after mouse over:

Seems like the glow effect will change its shape according to the image shape. Is this a NSShadow? How to implement this in code? Any clues or examples? Thanks a lot.

I could with iOS but I think the same applies:

• set zero offset for the shadow
• blur it enough
• give right size
• and choose white as color.
