I've never bothered using the L & S device for image streaming although I have followed some interesting imagry while using it.
If I want to image stream I just grab a tape recorder and image stream.
You can certainly use them with subliminals since most subliminals just have ocean or nature sounds they are not trance inducing in themselves. My orginal experience with subliminals led me to the conclusion that they did not work. However these subliminals did not meet one criteria that I now consider crucial. You must be able to hear that they are there. They must be barely audible so that you hear the voices are present yet too low for the conscious mind to follow so that the conscious mind gives up trying to give the message meaning.
For learning... like with language learning tapes much more interesting than just listening to the tape.
