Hi Clive,
I'm not sure that I understand what you want to do with the image, - do you just want to remove it as a bullet point?
If so, you would just need to remove the ul rule:
ul {
list-style-image: url(../images/bullets/tick_green.png);
}
from the end of your /css/haloeffect2.css stylesheet. You can remove it entirely, as it is already defined in your menu.css stylesheet. If this is not what you menat, could you post back with more detail?
cheers
