Background image for Extended Grid .. is it possible??

hi
i have an extended grid, with a few fixed columns . I need to set the background of the fixed portion of the grid with a color .and the second half with an image . is this possible ??
Can i set an image as a background of the extended grid ..
The following css does not seem to be working ...
#myGrid .aw-grid-cell {
background: url(img/17.jpeg);
}

Check the image path - this should work if you want to set background of each cell -

#myGrid .aw-grid-cell {
    background: url(/path/name.gif);
}

For the left and center panels in the extended grid use .aw-gpanel-left and .aw-gpanel-center

#myGrid .aw-gpanel-left {
    background: url(image1.gif);
}

#myGrid .aw-gpanel-center {
    background: url(image2.gif);
}

hi ... i need the picture for an entire grid .. not cell by cell ..
