You can upload sound, image or video files to all items. The icons are grey when nothing is uploaded. To upload a image file, click on the picture icon. 

There are three ways to upload a file. You can drag and drop it, you can browse your computer or you can search within the system for an already existing file. 

When the upload is complete, click Ok.

The icon has now turned blue.

If you click on a blue icon you can listen to the sound, see the video or image.
