Online Now Icon - Problem Options

[redciv2]

I am using this code to add a custom online now icon:

CODE

<style>
.a {online now icon}
.profileInfo td.text
{background-image:url(URL);
background-position:-10% 70%;
background-repeat:no-repeat; z-index:2;}
.profileInfo .ImgOnlineNow {visibility:hidden;}
</style>

...But the image is repeated in a few places. It's where it is supposed to be, repeated right beside that, and underneath my display name. Help?
