Hide a file in picture...
This is really a cool trick...even if there are no practical uses for it...

the only real requirement is 'WinRAR'
WinRAR is an archiving tool much like WinZip...also like Winzip the trial
version will continue to fully work with just a nag box...

To try this trick...Create an WinRAR archive of any file(s) you want (I've
tried several file types and multiple files) and place in a new
folder...also in this folder place the picture (only tried .jpg file types)
you want to hide the archive in...

now open a DOS command terminal (cmd.exe)...and navigate to the "new folder"

now just edit the command below to reflect your file names...and paste it at
the DOS prompt...

copy /b yourpicture.jpg + test.rar yourpicture2.jpg

The new picture (yourpicture2.jpg) will be created...for all practical
purposes it will appear and open just like any other .jpg file (the size
will increase accordingly with the size of the archive) it will open in any
image viewer or editor... but open it with WinRAR and there's your hidden
archive...!
