Grading takes longer without the ability to rotate student-submitted images in Speed Grader. I have to download, open and rotate images to view them correctly. Part of this problem would be fixed if students could rotate their images in Canvas as they submit them, which is a separate but related problem. But the ability to rotate an image in Speed Grader would be useful even then (since some students will probably not care to rotate their images). This would allow me to better add annotations to the image so that the student can see my feedback and understand it. I am facing this a problem in art class, but I imagine it would help anyone who is requesting image uploads for assignments.
