Can I keep using CoalaWeb Social Links when my subscription runs out?
YES - If you have purchased a CoalaWeb PRO subscription, you have access to PRO downloads, updates and support for the length of the subscription. After it has run out you can keep using the version you have installed. However, you will no longer be able to update to a newer versions or receive support. Of course you can renew your subscription to gain access again or you can choose to downgrade to the FREE version its up to you.
Not Easily - To allow the module to load quickly with all of the options displayed I have used a sprite (Whats a sprite?) where all the icons are in one image and I reference their location with css so the short answer is no you can't. Unless you want to modify the sprites being used and the modules css but that’s up to you. There is also the custom option where you can choose the image you wish to display.
