Can a popup (pinned image) :
1/ have a z-index in order to be covered with a simple image ?
2/ be closed simultaneously with a simple image when clicking on the popup ?
3/ be not permeable in order to be closed when clicking on it, even if there is the pinned image trigger under it ; that's what happens when you click on a painting on the wall, the popup comes and if you click on the popup to close it, if the initial painting is still under it, you can't close the popup: you have to click on the part of the popup which doesn't covers the painting on the wall, which is not instinctive.
Thanks for your help
