I've been correctly adding graphics to questions for months.

Lately I've been getting errors messages like the following...

I've tried opening the permissions of the PNG file but nothing seems to fix the
problem.
Does this occur for all problems in the course? If you clear the tmp directory webwork2/courses/physics_1401/html/tmp/gif/ of all temporary image files does the problem continue? And is the file in question present in that directory? Finally for those files there which are links, what are the permissions on the linked files (and the directory structure above them)?
