Well, I created MVC architecture for application that I'm working on, but using Atalasoft's library as Viewer part isn't that neat as it could be. Glenn, if you think MVC implementation with help of DotImage library could be interesting topic, open a new one, I would surely contribute by posting my problem/solution to that thread.
Thank you very much for the answer you gave me, it solves my problem as I currently work with only one layer.
