Online now present when offline, What's going on? Options

[thespianball22]

Ok, so I love the little custom online now icons that people have so graciously created for MySpace to replace that little ugly default one. I have used 3 custom icons: one on my page, one on my roommate's page, and one on my roommate's girlfriend's page. I have noticed an error though. The icons are present all the time, even when we're offline. I used the same code for each of our pages. The only difference is the URL because they are different icons. Here's the code I'm using:

<!-- begin code provided by createblog.com --><br /><style type="text/css"> table table table td.text div img {visibility:hidden;} table table table td.text div { background-image:url("http://img.photobucket.com/albums/v727/thespianball22/Ect/imhere3yb.gif"); background-repeat:no-repeat;} able table table td.text table table div img {visibility:visible;} table table table td.text table table div { background-image:none;} </style><br /><!-- end code provided by createblog.com -->

I am hosting each image at Photobucket instead of the server they were originally on.

Can anyone tell me why the online now icon appears even when we're offline? Thank you!
