I use that in a lot of Circuit VR posts so you can click on a circuit and see it live. However, the simulator does not save the source code in the virtual Arduino. You have to do that yourself.

The Image widget is designed to be a simple yet powerful addition to the Arduino Cloud toolkit. Users can upload static images in formats like GIF, JPG, or WEBP, with a size limit of 5MB.

The rig is based on an Arduino Uno and has a few circuit components that can be used as references and generates data on the behavior of the memristors under various situations.
