        右键－目标另存为－这两张照片，然后把后缀gif或jpg改成rar。如果没有显示后缀，可至控制面板（经典视图）－文件夹选项－查看中设置显示文件后缀名，或在图片上右键打开方式－选择程序－使用WinRAR打开。

        打开后，看见什么了？照片中竟然藏有两段各长达十分钟的3D片、一个3D游戏以及一个三维动画源码，而整个文件才300多kb大小。具体介绍，请看：

         下面介绍如何实现rar（包括7z）文件变jpg或gif。

How to hide a .rar in a jpeg file

Here’s some good old instructions that I found to hide a .rar file in a jpeg so that you can open it as either…

Get your .rar file and put it in the same directory as a jpeg picture (c:\hidden is a good place to put it)
Open up a command prompt by clicking Start/Run and typing “cmd” and click ok.

In the DOS window, type “cd c:\hidden” to navigate to the folder
Type “copy /b input.jpg + input.rar ouput.jpg
(where input jpeg is the picture you want to show, input.rar is the file you want to hide and output.jpg will be the name of the new combined file)

That’s it! You can double click the new file and it will show it as a picture, BUT… if you open it with winrar, you will see the files contained. The picture above has a secret file in it, right click and save picture to your computer and then open it with Winrar to see what I put in there!

rar变成jpg

假设为14.rar和14.jpg，然后把他们放在同一个目录下，假设为e盘。
然后开始菜单－运行－（输入）cmd－（输入）E:－回车－（输入）
copy /b 14.jpg+14.rar yisi.jpg。

注意的是/b一定要。加号的前面一定是jpg，然后出来的yisi.jpg就是图片了。传到网上。
看的时候右键另存为。把jpg后缀改成rar就可以用了。

         嘉林发现如使用右键－图像另存为会保存成bmp格式，失败。故应右键－目标另存为，或复制图片地址用下载软件下载。
