Yes, I know that it is possible to select and save media in the module. It works for me too.. That was not the reason for the problem, the problem is something else.
The problem is that it doesn't show up anywhere. If I save an image in the module, where is the image visible? It is nowhere to be seen. where does it appear? Where can I see the media stored in the module?
Explanation:
The teacher adds a module to the course content, names it "module01" and selects and adds a certain picture named "picture 01" to the module named "module01" and saves it.
So the teacher put picture 01 in module 01.
Who and where will see the picture 01?
Nobody!!! That picture (picture01) is lost, it is not displayed anywhere, it is not visible anywhere.
When the website visitor views the course details, he does not see the picture (picture 01) for module 01.
When the course is opened by a student, the 01 picture is not there for module 01 either.
So where is the embedded image (picture 01)?
Where did picture 01 go???
