No there is no step you are missing, you are just using a broken link. You just need to copy the correct URL of the photo, exactly as it is displayed on photobox and ensure the photo is not set to private and then paste the link into the image box here. It will then work.
As you will see it is a working link and the image shows. I would urge you to try this using the link I have provided in this post so you can see the system is working fine. Then if you can find the correct, working link from Photobox, you will be able to add your image too.
