Always post the command line used (or log file line two) so we know what you
did.
Always post the url of the page with the problem and the url of the link.
I suspect when have to click to enlarge the image. That's not an image that's
a web page so get non-html does nothing.
Depending on the url of the link you may be able to add a filter to enable the
link and then get non will work.
