If you check your fiddle with the inspector you can see that after the JS is initiated there is no data-attr anymore on the image. The problem is all the background stuff you are doing. Not sure how maximage works but it seems that.
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.
