I think you need using Images as well.

Please read

(Efectivamente aquí suele haber posts sólo en inglés.

prueba esto, debería funcionar

using ImageView, TestImages
img = testimage(“mandrill”)
imshow(img)

Actualización, no requiere el paquete Images para la visualización, ImageView es necesario
