Your UIImageView has a layer the contents of which you set to your image. The size of layer equals to the size of imageView, but size of image is less then it. So when you set contentMode to your view it says to it's layer to draw layers contents at bottom if contents size is less than layers size.
So size of layer (and as consequence size of its frame) are still the same even though you have resized its contents image.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
