It is not good practice to set an image in a widget using CF.widget. If the widget you are referencing is on a page which is not the current page, I don’t think this will work. It will not fail but as soon as you leave the current activity, if it actually did work, your changes are reverted. Instead, use GUI.widget() to retrieve the widget on the current page and set the image Note that GUI.widget also works from inside the Page script as well.
