Yes! vtkPNGReader can handle multiple files! It is associated with
vtkImageReader2 not vtkImageReader...

You can use a script like this for files "my_dir/im0001R0.png to
my_dir/im0348R0.png ":

vtkPNGReader *noduleReader2 = vtkPNGReader::New();

noduleReader2->SetFilePrefix(your prefix);
//the prefix contains your dir path and the constant part of your file name
: "my_dir/im"

noduleReader2->SetFilePattern(the end of your files);
//here it will be "%s%.4dR0.png";

 noduleReader2->SetDataExtent(your file extent....);
//or your spacing....

//your reader ready to be used!!!!

Hop it helps
