roSlideShow equivalent?

I know that roSlideShow is being deprecated.

Having a hard time finding an equivalent SceneGraph code chunk to display images from a CDN.

Any info appreciated!

Can’t help with the chunk, but if find you have to do it yourself, a slideshow seems like about the easiest thing you could choose to build with Scenegraph - relatively speaking.

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]

Did you ever figure this out? I’m new to Roku and trying to do the same thing!

Here is a simple slideshow I use. I use a timer to increment the item index every 6 seconds. I usually have a set of thumbnails underneath it that animates on itemFocused with a blurred fullscreen fading background but since I cant upload components and structures I shared a 1 doc component. Also you do need the standard content reader task to render the files.

<?xml version="1.0" encoding="utf-8" ?>
<component name="Slideshow" extends="Scene">
	<children>

		<Postergrid
			id = "postergrid"
			translation = "[ 0, 0 ]"
			basePosterSize="[1280,720]"
			useAtlas="false"
			posterDisplayMode="scaleToFit"
			itemSpacing="[0,0]"
			numColumns="2"
			numRows="1"
			drawFocusFeedback = "false" />

		<Timer
			id="testTimer"
			repeat="true"
			duration="6" />

  </children>
