Currently images can be inserted into glossary entries. This is very usefull for the visual learner.
But when you export a glossary with images in the entries using the XML option, the images are not stored as part of the XML file as the are with the moodle XML format for questions as in the question module of moodle.
I believe this would be a natural feature to add to the XML import and export for the glossary moodule so that you could copy a glossary of a particular subject area from your class to a different class easily.
I started a issue tracker for this, but it was closed. See MDL-28526
I thought this should get more input from the moodle community. So I have posted this thread here.
