Image and link not showing in sidebar, Twenty Eleven theme

I created a site using Twenty Eleven theme. Installed the plugin Widget context (so I can chose which pages to display widgets on).

I installed a “text” widget with Facebook image and link and it displayed fine, but now it has completely disappeared. The link “heading” displays but the image etc does not. Here is the code I used in the “test” box:

Thanks
