Hi Capsule Team,
I think the easiest method is uploading the test to my itch.io account so you can download it from there:

[UPDATE]
I substituted a webp background image instead of the original jpg and it worked fine... Something to think about...?! It would also be useful to duplicate a scene, or allow a background to run across several scenes - that would be efficient.
