Change the image and look of the share buttons

JFBConnect currently supports the Javascript sharing buttons from the social networks we integrate with. We've supported custom buttons in the past for specific networks, but not all of them allow for custom images. Because of that, we've standardized on what the social networks support natively. This also prevents Facebook and other networks from disabling or clearing shares from your site if they decide your sharing feature doesn't comply with their terms, which has happened before.

I hope that helps explain,
