Buenas:
Tengo imágenes .gif en un pictureBox que lo cambio al pulsar un botón. Lo curisoso es que se borra o desaparace la iamgen cuando cambio de imagen y no se porque es.
Tiene que funcioinar así.
Si pulso botón ON, se ve una imagen de una luz encendida. Si pulso el otro botón OFF, se ve la otra imagen del mismo pictureBox pero con la imgen de la luz apagada, así de sencillo.
