Yes, but if collage is widely published, the censors can use it to find 
the images that have the hidden articles, and block those and/or trace 
people downloading them.  AFAIK FlickR doesn't use https:, and each 
photo has its own URL, so it's pretty easy to find them.

  [ It's definitely nontrivial to do crypto right.  Even a strong
    system can be undermined by poor key management.  Theoretically
    unbreakable one-time pad systems have been subverted by poor
    operational practices.  This has been a problem ever since the
    very first ciphers were developed millennia ago.

    Like I've said in the past, bad crypto can be much worse than no
    crypto!  At least when you're not using crypto you assume your
    material can be spied upon, and you tend to manage what you say
    appropriately.  But if you falsely believe that you have a secure
    channel, you're likely to say far more, and the prying eyes will
    sparkle with glee ...
