Very Simple and painstaking work for Unity

I have 560 pictures. I create greeting card in unity and print it in file png in my documents in Unity 2017.1.0.f3. Need in code to find for pictures X and Y that fit the position on png picture. Also need to fix images in Photoshop. Very Simple and painstaking work. I work with Unity 2017.1.0.f3. No other versions will be accepted. I need to check the work via teamviewer time after time.
