Java - agrandar imagen a pantalla completa

Muy buenos dias:

Os comento mi problemilla haber si me lo podeis solucionar, o redireccionarme ha algun lao donde lo hagan.

Lo que quiero es en una web, aun sin subir a la red, que pinches en una imagen de una camara de seguridad y se habra esa camara en pantalla completa, vuelvas a pinchar en el video que se esta viendo y vuelva a su tamaño original.

Como puedo hacerlo? estoy buscando desde hace 3 dias y no encuentro nada. Por cierto no soy ni programador ni nada por el estilo, vamos que no tengo ni idea de programar.

Os pongo aqui algo del programa, para que veais un poco como va
