UMG image binding

Sorry but I still don’t understand how I do this without having one texture containing all the images. Can you explain how to use your approach without having every image contained in one material?

I read the UMG documentation before I posted here. I’m trying to figure out how to use the image as explained here

Image Displays the specified image. Currently this has to be a Slate Brush, however there are Blueprint functions on the Widget that allow you to set the image from a Texture or Material.

The last bit (that allow you to set the image from a Texture or Material) implies you can update the image
