 Yesterday in IRC I was refered to these two, so I mistakenly assumed them
 to be related (also in the second post there is talk about QR codes).

 That is of course correct. As I said, it would be nice to have plugins
 that allow for different types of approaches.

 Sorry about that, is there a ticket for writing 'BridgeFinder' or shall I
 open one?

 I took care to not make this mistake but then I still did. Excuse this
 newbie-mistake.

 What are your suggestions? I like the idea of image steganography as it
 allows for unsuspicious communication via email and hosting on websites.

 Of course this is correct, the images that are encrypted with such
 passwords need to be "simple" enough. I can also think of images that
 contain no password at all. But of course that would make it easier for
 censors to find them and block the bridges.
