Widget Blueprint: Image Overlaying Button Help

Under the Widget Blueprint editor, I was making a Level Selection screen where there would be an image in the background with a few buttons on top. When I place the image and the buttons on the canvas, the image will overlay the buttons makingthem inaccessible. I feel like this might be an easy fix, but I am new to the engine. Also, for some reason only the first button is overlaying the image while the rest of the buttons are underneath.

easy, change the ZOrder under Slot in the details panel

And if you want to still click on the buttons but have the image on top of the buttons?
