Media page

Images, audio, video, PDFs, captions and stylesheets, and how to add them from the editors.

For authors

Media files are resources of their own. The Resources page lists them with the type webcontent; each has a page, opened from its row.

Preview

The file shown the way a browser shows it: an image, a player for audio and video, a PDF viewer, or the text of a caption file. A resource with several files (a portable custom interaction’s modules, for example) lists them, and you can choose which to preview. Size, dimensions and duration are shown when known.

Usage

Every item, stimulus, section and test that refers to the file. It cannot be deleted while anything does.

Metadata

Descriptive records, as for items, plus technical details (format and size) read from the file.

Uploading from the editors

You add media while you edit, through the media picker. It opens when you:

• insert an image or object from the Inline menu, or insert audio or video;
• press Choose… beside a file address in the properties panel;
• link a stylesheet from Item properties.

The picker lists the bank’s media, newest first. Search by file name narrows it. Choose one, or Upload a new file (drop it on the picker or choose it).

Allowed files are images, audio, video, PDF, captions (.vtt) and CSS, up to your site’s size limit. AIB checks that the file really is what its name says, and refuses an SVG or stylesheet that could run code.

If you upload a file the bank already holds, the picker says so: Use it to refer to the copy already there, or Upload a copy to store it again.
