Problem

InfoPath complains that you have a linked image when you are trying to author a forms services (browser) enabled SharePoint form.

Solution

• Select Design Tasks > Views
• Create a New View (bottom of Design Task’s Views windows)

• Copy the contents of your offending view to the new view
• Delete the original "offending" view
• Refresh the compatibility settings an voila, all good!

Explanation

No explanation, this is clearly a bug.  This usually happens when you copy and past an image into your clipboard.
