Replace image on click further instruction

I have read through a previous “replace image on click” thread but I still need more specific help. I want to be able to click on an image and have another image replace it. I tried layering one image on top of another and creating a click interaction that fades the bottom image out and another click interaction that fades the top image in. But that requires two clicks. Any suggestions on how to better approach this?
