Hiding the extended network

Install this code in your profile :

<style>
.extendedNetwork {
display: none;
}
</style>


Put an image instead of the Extended network

Install this code in your profile :
<style>
.extendedNetwork {
background-image: url(http://www.images.com/yourimage.jpg);
background-repeat: no-repeat;
border: 0px;
}

.extendedNetwork .blacktext12 {
display: none;
}
</style>

Just change the “http://www.images.com/yourimage.jpg” link with the direct link of your image.
If you want your image to repeat itself (like a mosaic), remove the background-repeat:no-repeat line;
