I need to view the source of a webpage. This web page is a plain text page with some text regarding an error. But the page's content type is set to image/jpeg. If I visit the page in Internet Explorer or Firefox, the view source option is greyed out. How can I view the source of pages with content types not set to text/html?
Edit: This page is not actually an image, it is a plain text page with the content type of an image.
