Thanks Dave! I deleted the old subtopic item and successfully uploaded a page with the image included instead. (That feature didn't exist when I first published the text, and at that time a subtopic seemed to me like a page with the additional option of adding descriptive links - so why be tied to the mast, so to speak.)
The description attribute for the page isn't displayed at the right place, though. I expected it to be displayed after the Curriculum Sequencing Model link on the parent (index) page, but now it appears in bold letters at the top of the content page (in a new revision, which I don't want to commit as the live revision).
This is not intended behavior, is it?
