To add a link to an image, click on the image. When the image is selected, there is a toggle switch in the right column that says “Link”. Click the toggle to enable it (it will turn blue), and a “Url” field will appear below it, where you can type the link URL.
This is how you can do it in the new version of Chamaileon editor:
Click on the image, then click image properties on the right side of the toolbox and turn on the link switch.
Set ''HTTP'' as protocol and add your link in the URL box below.
