To add images to discussion boards, wikis, and blogs in the online course platform: 1. Click the Polaroid icon in the text editor to upload an image from your computer rather than attaching it. 2. Select the image and click "no" to not launch it in a new window. 3. The image will appear in the text box where it can be resized so the entire image is visible without being too large for the screen. 4. Add text, then click "post entry" or "submit" to share the post with images.
