Thank you very much, that was it. I disabled my navigationblock and so I could not see the manual grading link.

This is the closest I've gotten:

Click "Grades" in the Settings menu. The "Grader Report" should be the default, as before. Click the name of the quiz in the top row of the Grader Report. That will bring up this page:

.../mod/quiz/report.php?id=XXXX&mode=overview

At that point, you can see a list of the attempts and are given a link for  ones that are "Not Yet Graded."

The link above is similar to the one given by Gerrit in the first post to this discussion, but the /mod/quiz/ part is important for finding your way to the correct place. If you just put report.php? etc in place of view.php on the main course page, for instance, you won't end up in the correct place at all. Also, the id number I've represented by XXXX in my link is the id number for the QUIZ not the COURSE.

Hello James,

Short story:

Yes it's allowed for you and disallowed for students and really you should not try to change that.

Also I think it would be best to stop using copy/paste even for admins and teachers and use the recommended way to insert images with the editor's button.

Long story:

When you copy an image somewhere and paste it in a Moodle editor (when testing I was logged as admin and used Firefox and Moodle 2.7 with Atto editor but I think it is the same for teachers and with other browsers and Moodle versions with the TinyMCE editor) image is not included in the usual way, rather than an url the src parameter of the <img src= ...> HTML tag is something like data:image/gif;base64, followed by a long string containing the image encoded using base64.

This works for admins (and maybe teachers, not tested) but is completely forbidden for students. So if they try to do this, latter when their response is cleaned (all texts entered by students are cleaned and if they try to enter something potentially dangerous for instance some JavaScript script, it is suppressed for obvious reason) this part of their response is suppressed and the image disappear.

You may wonder why this "data:image/gif;" HTML fragment is also cleaned. I must admit I am not a security expert, but I know it could be exploited by some hackers to do nasty things , so this is why it is removed, and you should not try to permit your student to include such content.

I also believe it is not good to use this method to include images in your questions yourself.

• base64 encoding increase the size of each image so this is not good for instance in backups/restore where we know inclusion of the question bank may already be a problem when there is a lot of questions.
• if you copy the image from an insecure source you may yourself introduce some malicious content into your Moodle.
