I have encountered a very interesting problem about img src which change on a:hover.

[SCREENSHOT](http://img7.imageshack.us/img7/7038/sywe.png) 

As you see, hovering the `<a>` sector,you cant see logically the white img. So I had the same icons on black and white, I want on hovering the sectors of #menu, the img src changes img links to black icons, instead of white, which are for only non-hovered sectors.
