A Joomla component for managing files in the /images/ folder or other user-defined local folders. The media manager allows you to organize media content in a folder tree, upload individual items, perform some basic image editing functions, and place images and links directly into articles.
Multimedia (media files) are images and files that are used in Joomla as illustrations or links in articles, modules, templates, and so on. An important feature of media files is that they are delivered directly by the web server without being processed by code. This is fast and efficient.
FYI
In Joomla, media files are stored by default in the /images/ folder, which should not be confused with the /media/ folder, which contains JavaScript and CSS files.
