Unable to set image on button widget when player interacts with it


I have a button widget with an image child attached. I would like to change the image that is showing when the user interacts with it. I have the interaction with the 3D widget working fine after following this tutorial.But I can’t figure out the logic or what blueprint components to use to do the swapping of the image. Here is the blueprint I have so far including the hierarchy and variables:

But, I am unable to figure out what to drag in to the set image window.

Is there a simple obvious solution here that I don’t know about because I’m new to UE4? Or am I going about this the completely wrong way? Might give up and just set a text character on the panel instead, but it feels like there should be a way to do this that isn’t too crazy…

Thanks in advance for taking the time to look at this!

You need to set the brush texture on the image:

Thank you!
