I know I've come across this before, but I forgot.
It's seems that it is not possible to have a folder resource WITHOUT force downloading of the files,
See: https://tracker.moodle.org/browse/MDL-28501 regarding HTML files (The discussion has kind of faultered, unresolved) and the discussion here: https://moodle.org/mod/forum/discuss.php?d=184088
I thought this was so obvious a need that this would get fixed in due course.
Q1: is there a way to NOT have force download of image files in a folder (ie just to view them) ??
Q2: if Q1=No, is there another way to simplly deploy a bunch of images so students can view them?
Q3: If Q1=No, what are your thoughts on a tracker request for (say) PNG, JPG and GIF to be viewable without force download?
ie is there a security problem with images?
