I don't think so. Replacing the low-order bits of a picture with
random noise (or an encrypted message) is silly - like you say, anyone
can find it easily. But there is a certain amount of free entropy in a
picture. And if you create a data stream to match its statistical
properties, and you hide it there, no one's going to notice.

Of course, this isn't easy to do - "matching statistical properties"
isn't a simple closed problem. But I bet you could do fairly well in
certain circumstances. For instance, Linux uses a strong random number
when starting a TCP connections. I bet you can hide a few bits of data
in there and no one will see it.
