Plugin problem

I have a blog which was done on WordPress. I wanted to add a Social Media Plugin and used, at WordPress’ recommendation Social Media Feather. Now every time I click the button to share my blog with Facebook etc, the following happens: Social media plug-in is pulling the header graphic from the blog and there is no way to prevent it from happening. It looks terrible.

Any thoughts on how I can fix this?
