How to add an image in the body of a Forum Post or Group Discussion instead of adding it as an attachment. Using the 'attachment' option would be best for Word Documents, Excel, Files, Powerpoint, etc. Images are best added right into the post so they are visible without having to click on the attachment.
See the red arrow in the image below. By clicking on that, you can select your image and add it right into the body of the message. If you wish to add another image just click it again.
Below is a short video showing how to do it. This was made before the site colours were changed but its the same procedure.
