In an article editor, the Iris - Media button opens the Iris media library. A double click, or the Insert into the article button, places the file at the cursor.
An image
Iris inserts a plain image, with its address, its size and its description as alternative text. If the image is not described yet, Iris offers to describe it before inserting it, or to mark it as decorative. The HTML it places stays readable without Iris.
A document
A document becomes a link that announces its format and size, "Annual report (PDF, 1.2 MB)", with a card: thumbnail, details, Open and Download buttons. Four layouts to choose from on insertion: Tiles, Image on the left, Image on top, Compact list. Downloads are counted in the file's details.
Replacing an image
Select an image in the article, then click Iris - Media: the media library opens on its folder, and the button becomes Replace in the article. The chosen image takes the place of the old one.
Enlarging on click
On the site, an inserted image opens large in the viewer when clicked. The Enlarge article images setting (Options → In Joomla) chooses: those inserted by Iris, all article images, or none.
Joomla image fields
Joomla image fields (intro image, full image, a module's Media field…) also open Iris instead of the Joomla window. Image fields setting, in Options → In Joomla.
