No, that's not crazy, it's just crazy to think that anyone is going to notice someone doing stego in an internet cafe, since anyone doing stego is already going through huge efforts to hide what they are doing. The idea behind good stego is that you encrypt something important, stego it into an image, then post that image (i.e., dead drop it) somewhere where the recipient knows to look. But when this is done (on either end), of course, all that appears is happening is that the person is either upload or downloading an image. When you consider some of the Usenet groups out there with bajillions of images posted a day to them, this would probably be a pretty effective system, assuming your stego program is good enough to embed the data into the image itself and is not just encapsulating it into the metadata or something. The one interesting thing to come out of this sheet is that apparently terrorists are heavy stego users.
