How I should understand difference between images and media directory? In all my Joomla! sites I was using images for image files displayed in articles, media for PDF's, MP3's etc. Names of these directories led me to do so.
(1) If I have 600×900 px (portrait) banner image which on click goes to 6000×9000 image suitable for large-format printing, should the former go to images and the latter to media directory?
(2) Name media evokes me either abstract media type (PDF, EPUB, MOV) or CSS-like display media (paper, screen, mobile device) or storage media (DVD, HDD, CD). How should I understand directory name media from Joomla! viewpoint? What media are expected inside?
(Main) What is the main rule for decision which directory to use for what?
▶ More than simply learning DO's and DON'Ts my goal is to understand intention of Joomla designers for these directories.
