For those asking about a legit use, consider this: Some FOSS projects make really large release files (like linux distros, with ISO sizes of 700mb). It can be hard to get mirror space for these files. However, hiding the file inside a .jpg is a way to trick many CDN’s into hosting the file. Then, a crappy server can be used for the mirror and downloads will still work.

i dont really get why you are using > instead of >>
i tested your cat commands, and also this one:
cat archive.zip >> pic1.jpg

and really there is no difference at all. both extract the files in archive.zip
it is just that using >> seems more neat than >

Ok.. that’s fine. Large files just wouldn’t be very hidden. It would be like hiding a fat man under a carpet. It’s only practical to insert relatively small amounts of data into an image (or other file). Otherwise, why not just encrypt the fat man- er.. data.

It is good if you have copyright data to send to a frind that you do not wish your ISPs or the gov to see and on Linux you can password zip files.
and you can send odt file and word doc in jpg to make your e-mail private.
