How do you transfer a picture from a page onto another surface?

I once saw an artist soaking magazine pages in a clear liquid and then transferring the picture onto his canvas, or whatever it was that he was using for his art. I have tried turpentine, but this was not successful. The picture was not pasted onto the new surface, but instead, he just got the image onto the new surface and peeled the actual page off, with the pitcure transferred. I am looking to transfer printed pictures onto a white box without pasting them. Any ideas?
