the uploaded image is processed on all canvases. Show slide-shaped

If you can do that, I can invite a lot of people.
You can achieve that by placing an default image to every view and give it a "Replace" value. Then set the same "Replace" value for custom images and enable "Replace in all views" in the settings.
Now when the user adds an image, the image will be added/replaced in each of your views.
