Many of the new iPads and iPhones have HEIC files for their photos. If a student is required to upload a file to Canvas this file isn't compatible with the speedgrader preview. In order for a teacher to view this, he or she must download each individual document and then open them. This is extremely cumbersome, time consuming, and takes up a lot of space. Is there any way that the HEIC files can be added to the list of files that automatically preview in speedgrader? The example I would use would be if a teacher gives her students a math problem to work out. She wants to see their work, so they must take a picture of the page, then upload that picture to Canvas. Using the new iPhones causes the picture to be in HEIC format which is not compatible for preview in speedgrader.
