Changing hover Image.

I can set the image for my tabled forum for each of these 2 area, Table 1 and Table 2.

I am using this CSS code to construct a hover effect and set the images.

Code:

td.row1,td.row2.over:hover {
    background-color: #2f2f30;
background-image: url("http://i656.photobucket.com/albums/uu281/Sickmood/stone2.png");
}
td.row2,td.row1.over:hover {
    background-color: #2f2f30;
background-image: url("http://i656.photobucket.com/albums/uu281/Sickmood/stone.png");
    }

Only 1 of them will highlight into the other, How would I get both to highlight to each other?
