How to show social networks in gray scale in widget contact info?
What's the path of the picture that is used to render the social networks?
Just for info, my intention is to show the icon deactivated when the featured addons expire.
So, I'll implement such behavior and show both image in gray scale and a title saying that is expired and needs to be renewed.
