How to Hide Secret Documents inside JPG Images

Turn out that it is actually very easy to hide (or embed) other file inside a JPEG image. You can place video clips, pdf, mp3, Office documents, zipped files, webpage or any other file format inside a JPEG image.

Let's say you want to hide a confidential PDF document. What you can do is convert that file into a regular jpg image so even if anyone double-clicks this file, all he will see is a preview of the image and nothing else. And when you want to work on the actual PDF, just rename the extension from jpg to pdf.

Step 1: You will need two files - the file you want to hide and one jpg image - it can be of any size or dimensions. [If you want to hide multiple files in one jpeg image, just zip them into one file]

Step 2: Copy the above two files to the C: folder and open the command prompt window.

Step 3: Move to the c: root by typing cd\ [enter][if the files are in another folder, you'll have to change the prompt to that folder]

Step 4: The most important step - type the following command:

copy /b myimage.jpg + filetohide.txt my_new_image.jpg

Step 5: To see the original TXT file, just right click--> my_new_image.jpg and open with notepad-->go to end of file you will see your secret message.

Here we illustrated with an .TXT file. If you want to apply this technique to other file formats like XLS, DOC, PPT, AVI, WMV, WAV, SWF, etc, you may have to first compress them in RAR format before executing the copy /b DOS command.

To restore the original file, just open file with winRAR or 7-zip.

How to extend Windows 7 trial to a full version

If you install Windows 7 and don’t enter an installation key, the 30-day activation clock starts. To see how many days you have left, click Start, right-click Computer, and choose Properties. At the bottom of the dialog under Windows Activation, you’ll see the number of days left in your trial period.

When that number gets close to zero, you can extend the free period another 30 days via the following steps:

• Step 1 : Click Start-->All Programs-->Accessories. Right-click Command Prompt and choose Run As Administrator. 

• Step 2 : Type the following command and press Enter

slmgr  -rearm

• 
  

•  Step 3 : Restart Windows 7.

Once the OS restarts, the Properties dialog described above will indicate that Windows 7′s activation grace period has been reset to a full 30 days.

You can run the -rearm trick a total of three times. If you perform a -rearm at the end of each 30-day period, you end up with 120 days of full, unfettered Windows 7 use without having to supply an activation key.

Cool javaScript tricks

Today, I will list some very cool JavaScript hacks and tricks that you can use creatively or just have plain fun. To make each one of these codes work, all you have to do is copy and paste it into the address bar of your browser window and hit “Enter”. So here they are :

• Edit any page/website in real-time :

javascript:document.body.contentEditable='true'; document.designMode='on'; void 0 

• This piece of code pulls off all the images from your web page and rotates them in a circle. Really makes any page go naked (without its images). The best place to test is a website with many images. (Google Images for an example) 

javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.getElementsByTagName("img"); DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=(Math.sin(R*x1+i*x2+x3)*x4+x5)+"px"; DIS.top=(Math.cos(R*y1+i*y2+y3)*y4+y5)+"px"}R++}setInterval('A()',5); void(0); 

• The Calculator : In case you are not in a mood to use the standard windows calculator and want your browser to do the dirty job for you, use this code.

javascript: alert(34343+3434-222);

You can change the numbers according to your choice and also try creative complex equations. Just put your arithmetic into javascript: alert( );

• I have used Edit script on my google page and save it. Now when I open my firefox browser it shows image like above.
