This works by copying the compressed file in binary mode onto the end of the jpeg images. When the picture is opened, the jpg header says the length of the data and ignores everything below (the hidden zip file).

In this video, we are showing you how to hide files, of any filed type inside the regular JPEG image as many files you want. If I double click this image, it is a “secretcow.jpg.” It is a picture of a cow. It is a regular picture if I get a view, thumbnails, it is still picture of the cow. However, if I get list and here is the trick if I get of 7-Zip, Extract here, it shows me that I have several files inside this picture. And I used seven 7-Zip by igneous WinZip, WinRAR, WinAce or any type of compression software. As I assumed to use zip because it is free. It is open source and it is really small. It is like how you care. So how do I do this? First, I get the files I want to hide “secret_documents.doc”, “private_pictures.gif” and “hidden_video.avl” and random picture of the cow. So I can use any pictures, I do not have to be other “cow.jpg” and I think it does not have to be the JPEG. It is really does not matter. So, the first thing I want to do is select the files I want to hide. There selected and I am going to get again use the compression software. Use WinZip, WinRAR and any type of concepts when you have to add to archive. So, I am going to add this to archive and I am going to put in some zip. Zip files because that is the default on 7-Zip. Okay, it is compress. It is in the archived and now I can delete these files because all this files are inside “x.7z.” Now the question is how do I merged this two. How do I put the compress file and have it in the “cow.jpg” so that when I double click the “cow.jpg” picture it does not give me an error. I am going to get start run or windows key R and it is going to give me the command line, the run prompt. Then I am going to type “cmd” to get the command line. So here I am in the default folder. I am going to go back step by going “cd\”, enter. Now on the C drive, it is a lot easier if you just move these files to the C drive. My C drive is kind of clutter so I have it in folder called X. Now I am in a folder called X so here where its get cool. Here is the magic code. I am going to type “COPY /B”, that is stands for binary copy. The image name “cow.jpg” plus the compress file “x.7z” and the new file name “secretcow.jpg” and that is it. That is all the code that you need to type. Go ahead and click enter. Stop the video to copy this. One file copied and I do not need the command line anymore. That is it. I can delete the original archive, the picture of the cow. Now I just have “secretcow.jpg” and again if going to any type of extracting software, click extract here and I have the files that are inside and that is it. It is very simple trick. I just go ahead and extract to begin. If you want to be paranoid what is suggest you do is archive the files, add to archive, and compress it. Take away the extension, add to archive again in a different type. Like Tar something bizarre and finally then you compress the archive and the image but that is a little too far. You can also delete the header. Go into your hex editor or something and delete the header. Maybe the first three bytes save it in the text file and compress it. Along with the new “x.tar.” This has been a video tutorial by JimmyR.com. Checks out for more videos. Subscribe if you like this.
