Hi,

The question is in the title.

I tried that, but I only got a black square instead of the image.

```
vtkNew<vtkPNGReader> reader;
reader->SetFileName("icon.png");
vtkImageData* icon = reader->GetOutput();
...
vtkSmartPointer<vtkLegendBoxActor> legend = 
vtkSmartPointer<vtkLegendBoxActor>::New();
  legend->SetNumberOfEntries(1);
...
  legend->SetEntry(2, icon, "Label", color);
```
