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 ...
