We can't add code to page events while a full screen picture is placed
I apologize that there was no response before now.
At least in recent versions, setting the page .sta to image and then .pic attribute to your full sized image will now allow you to have page events exposed.
It is generally not within best practices to use a full sized Picture Component as it will cause issues in refreshing your components on top of that pictures as it will give a flicker effect.
Due to the time that has elapsed and several new versions since released, I will mark this as solved.
