The Options button, at the top right of the media library, opens the Iris Options. Six tabs.
In Joomla
- Image fields: Joomla image fields open Iris.
- Enlarge article images: those inserted by Iris, all, or none.
- Layout of an inserted document: the layout offered by default.
- Fingerprint of an inserted document (3.0.301): shows the SHA-256 fingerprint under a document inserted on its own (see Documents and PDF files).
Galleries
- Viewer: the default viewer for galleries, Classic (arrows and cross) or Iris (written buttons). Each gallery, menu item and module can choose another (from Iris 3.0.055).
- Custom CSS: rules added on pages showing a gallery, for what the settings do not cover.
Upload
- Rename on upload and Name pattern (
{dossier}-{n}by default), with a live example. - Ask before uploading: the window that shows the names before each upload and lets you keep the original names (Yes by default, from Iris 3.0.056).
- Maximum width and Maximum height: the frame, 1600 × 1200 px by default. It is also the frame used for lightening.
- Compression quality: 85 by default.
- Convert to WebP on upload.
Badges
Maximum size: above it, an image carries the too heavy badge. 300 kB by default. An image larger than the frame carries it too.
Formats
The status of PDF thumbnails on your server, and the formats Iris adds to the media manager: Recent Word, Excel, PowerPoint (yes by default), SVG images (cleaned on upload), 3D models, RAW photos, and a free list. Iris only removes what it added.
Permissions
The usual Joomla permissions. Image lightening, which modifies content across the whole site, is reserved for those who can administer Iris.
The System - Iris plugin
In System → Plugins → System - Iris: the watched roots (images and files), folders managed by other extensions, folders excluded from the report, template file scanning, resized variants, extra columns to scan for a third-party extension (table:column), cache lifetime, and the badge on used files.
Up to date for Iris 3.0.302. Features added after 3.0.045 show the version that brings them.
