Thanks to Miklos for helping me out!
Finally, in the morning hours :-) I figure out my problem and succeed to
input a multiple number of images!
my mistake was in the file myPlugInView.cpp
I simply added the command:
myFilter->SetInput(image);
and it works perfectly!
before of that, I didn't realize that the command:
myFilter->setMacro(image);
isn't good, because the software doesn't understand that setMacro is
actually setting an input image which it needs (although this SetMacro is
an image).
Thus, the software needs exactly the right command: SetInput(image).
