recently I picked up a trick from a youtube video about how to hide archives like rars and zips in an image file. First you make sure the image you want to use and the archive are in the same folder, preferbly directly in the c drive cause its easier. Go to the cmd prompt and if it starts in the wrong folder type cd\ and hit enter until your in the c drive once there if your stuff is in a folder you type cd foldername and hit enter. Get to the folder the stuff is in. type this with the exact names of your pics and archive :

COPY /B nameofpic + nameofarchive nameyouwantofpichidingplace

it may take a while to work when it does type thing will appear again and you should have a new pic with the name you gave it... then just use your extracting program to get to the files you hid. and it will also normally as the pic you used too ^_^ its the perfect hiding place.

that is genius I've gotta try that as soon as i get on a pc tomorrow morning. tho techically that may work on a linux system as well
