Jpeg Bandit simply makes the process of hiding archives with jpegs easier, without all that messing about with the command prompt! Also, it's 100% portable, so you can shove it on your memory stick and extract/encrypt on the go. There are some limitations, for some reason you can't use jpegs bigger than 500kb as it won't work, not sure why, but I shall look into this more! Also currently you can only extract RAR jpeg-archives using Jpeg Bandit, but any others you should be able to extract using your favourite archiving software (I'm personally voting WinRAR here..). Plus, you'll have to make the archives yourself before hand, but that's something I may add.
It's hopefully very user friendly and seems to work fine, but email me any bugs at firstname.lastname@example.org.
