I would like to reproduce and use a function that I saw in one of the first presentations of Publisher. It was about text on the picture with the climber. I saw that it was possible to draw a rectangle (Designer) behind the (multi-column) text and the photo area under this rectangle could be blurred with the box blur (Photo) so that the text in front of it was easily readable. I am not able to reproduce this effect: I always have to create a duplicate of the photo, place this duplicate photo in the rectangle. But this is not the solution, because every time I change the layout I have to duplicate and frame the picture again. What am I doing wrong.
