Quizzes

Lockdown Browser quizzes: The resolution of this image is too high to display message

Issue: For quizzes that require LockDown browser that contain images, students are seeing an error message in place of an image. LockDown Browser does not cache images (like a standard browser does) and overly large images can result in problems with LockDown Browser loading the page. Details regarding this error message can be found here.
Fix:  The instructor would need to resize the image. A size of under 9 megapixels is necessary (A resolution where width x height is less than 9 million). Once the image is resized, LockDown Browser should be able to display it.
