I've been asked to put a Hotpot quiz up for someone, having edited it to include images. And noticed the plugin has gone from our moodle, so I installed it on my test v2.3.1 installation - which said Success.
Firefox is complaining about how the URL of an image has been interpreted. I've never had a problem embedding images into a Hot Potato quiz before by using the <img> tag. The quiz is attached.
Any ideas appreciated. The tutor in question is off for a few weeks now.
