You can embed all kinds of content in your course lessons and tests. This tutorial explains your options.

There are three basic ways to embed other content in your courses:

Upload a media file and use the embed code to include it in lessons and tests.
Paste a URL from one of the auto-embed services to include it in a lesson or discussion.
Use the HTML editor in a lesson to embed content using an iframe.

Auto-embeds

Auto-embeds work simply by pasting the content's URL right in the text of the lesson (or discussion post). This works with:

YouTube
Vimeo
Scribd
Prezi
Instagram
Image URLs: Paste a URL for an image with the following formats: .jpg | .jpeg | .png | .gif | .bmp.

Here's how to embed that content in your courses:

Copy the URL of the media you want to include from one of those services.
Paste it into the lesson content editor.
As soon as you save what you're working on, the content is now embedded in your lesson.

iframes

An inline frame—or iframe—is a way to embed one web page within another. In general, iframes don't work in Populi—done poorly, they present a security risk. However, Populi does allow iframes with content from certain whitelisted sites.

Here's how to embed content using an iframe:

Grab the embed code. Different services have different ways of doing this. Some, like Spotify, require a paid account to get the embed code. Whatever you do, make sure you get the embed code, and not some sort of "share this" link!
Open the HTML source editor in your lesson.
Paste the embed code directly into the HTML source editor and click Update.
