Beginner question about disappearing image....

So I've been following the tutorials on the NodeBox site. I'm still confused as to why often times when I load a new Node into the network, my entire image disappears, even before changing the existing routing. My impression was that this happens because when adding a new node, it can only show one thing at a time. However, even when I click back onto my existing nodes, as I had before to view the image I was creating, its no longer there at all. I don't understand why it would disappear before even routing the existing image configuration to this new, I would imagine, unused node in the network.

This happens when I attempt even to Colorize my image. I'm quite confused. This is my first time using any program like this so if this is a childish question, apologies. However, I'm very intrigued and interested in this and would like to understand why this is happening and I have no other resource with which to attempt to satisfy my misunderstandings about why this happens.

I hope this explanation is somewhat clear and someone is willing to help me understand this.

    NodeBox can only render -- or show -- one node at the time. Often this is the node at the very bottom. We call this the rendered node.

    You can see which node is the rendered node by the little triangle in the bottom-right corner.

    When adding an element to your composition, you often need to use a combine node to show two things at the same time.

    The basic examples show off the combine node. Go to File > Open Examples and click on the "Primitives" example to see the combine node in action.

    You also might want to read How NodeBox Works to get a deeper understanding of the rendered node.

    If there's anything more specific, don't hesitate to ask.

    Thanks for the response. Also, thanks for pointing me to those examples. I hadn't even seen those example files within the program, nor had I seen that particular page that you linked which is immensely helpful. Thanks!
