I am new to Scene Graph. I too am interested in how we can easily create a slideshow from CDN content. A looping picture frame. I tried using the FadeScreensaver as a channel, but the images do not show. I think it is expecting images within the app pkg:/ folder itself.
BRIGHTSCRIPT: ERROR: roSGNode.AddReplace: unknown failure: pkg:/components/ScreensaverFade.brs(7)
ScreensaverFade.brs Line 7:
m.BackgroundArt.uri = m.pictures[m.count]
