Image file & zip file

I just read the forum that give tut about embedding file to jpg image file. However, this tut only available, as far as i know ( havent search thoroughly) only run on windows platform by utilizing "copy /b" on the MS-DOS command prompt. The following was the instruction:

1. Winrar or Winzip will be required for the file fusion process and the extraction process.
2. Shrink the file to .rar or . zip file format
3. Move on to the command line for the and put the MS-DOS instruction: "copy /b file1_name .jpg+ file2_name.rar/zip dest_file_name.jpg"
4. Woalla done...check up the result using the zipper application
   

Enjoy Blokes....

Follow up...encrypting the file and embed it in the image

C ya next time
