Brad is right, separate your problem into its independent pieces.
Rather than storing temporary, I would store it permanently and do some default resizing/cropping initially. Then, if user wants to edit the default results, there would be additional interface for this.
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.
