You can show a proper image viewer outside the view layout as shown here: [https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Show\_a\_slice\_view\_outside\_the\_view\_layout](https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Show_a_slice_view_outside_the_view_layout)

If you want to convert a numpy array to QImage then I would recommend to use qimage2ndarray package:

```auto
try:
    import qimage2ndarray
except ImportError:
    pip_install('qimage2ndarray')
    import qimage2ndarray

import numpy as np
image = np.fromfunction(lambda i, j: i + j, (100, 100), dtype='uint8')
qImg = qimage2ndarray.array2qimage(image, normalize=True)
pixmap = qt.QPixmap.fromImage(qImg)
myLabel = qt.QLabel()
myLabel.setPixmap(pixmap)
myLabel.show()

```
