UIImage imageWithData: returns an autoreleased object, which should not be released by you again. So this code snipped contains not a memory leak but the opposite, a double free (in the worst case).
Both imageWithData and dataWithContentsOfURL return autoreleased objects, so you should have no memory leaks in that code snippet.
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.
