I went into demo.moodle.org and Features Demo (English) to see how an image displayed in a branch table and what the Page source code looked like as a student. Ooops.
Like anything else in life, things have changed since we updated Lesson in the Features Demo ( think that was over 2 years ago). These changes may impact other demonstration sections, just be aware if this is of interest to you.
I would suggest this could be a good time to add other students besides our "Sam". Gradebook and a Quiz Item analysis are pretty pathetic when there is no data
However, suggesting such a thing probably means I should be considering a plan for doing it ....but then there is 2.0 around the corner and maybe later is better.
Best to all, Chris
