I have come back to this problem. I wish to send my students a html file with an image. I have created a separate html file for the students to do this. The file is in the IDE and not classroom. I have shared the file and it seems that the students can write over it. I have tried to make it private and share it and still the student seems to be writing over it.
Here is the link
What would be your suggestion to this problem. Thank you.
