I have students submitting photos of their written work (math assignments & artwork) as images. Instead of attaching them, they are adding them within the comments section. I do not have the ability to zoom in or rotate the images, many of which show up rotated 90 degrees count-clockwise. The angle and size make them difficult to read and grade.
I would love to see (a) images in the comments disabled so student have to upload the image as an attachment, or (b) tools added that allow me to click on images in the comments so they can be blown up and rotated.
