hmm i dont know what following does mean:

Code: [Select]

MyPicture(const MyPicture& Copy) : Image(Copy.Image), Sprite(Copy.Sprite)

what does ":" effect?

This is the constructor initialization list, which is the place where the class members are constructed.

so in this step not only an instance of MyPicture is created but also its members?

Of course

And they are automatically copied in the class copy constructor, assigned in the class assignment operator, and destructed in the class destructor (unless you provide your own version of these functions).
