My first "image with a pole" was a mistake. I just realized the vertical element in the centre of the image when looking at it later. I had blinded it out when taking the picture, my attention having been attracted by other things around it.
Since then, I have become quite fixed on vertical elements in our daily surroundings. I've collected lots of these images. It's still hard, though, to make an "image with a pole" by purpose, to arrange a picture around a pole in order to make the pole somehow 'invisible'. Therefore, many of these pictures still have been taken by chance.
