Hide important files inside an image

I posted about Make the folder invisible to hide "important" files before, and now here's another method on how to hide important/confidential things in an image. The result image will be exactly the same as a normal image (except the file size may vary depending on your hidden files). The image can be used solely for hiding confidential data, or it could be used to send confidential data over the net too.

For this, you need an archiver, like 7-zip, and a picture. A jpg would be good enough.

First, use command prompt to access to your picture folder. To open command prompt, go to run and run cmd. Windows vista can just search for command promt in the startbar. Use the cd command to change directory. For example below, my picture is place on my desktop, in a folder name "post".

Now, archive your files using your archiver. For this post, I will demonstrate this using the 7-zip archiver. Put the archive in the same directory as your image file.

In the command prompt, type in COPY /B image.jpg + file.7z output.jpg as shown below.

A new image file should have appeared in the same directory as your important files and the original image. Notice that there are no difference between the original image and the new image that contains the "secret" (except for the file size maybe). You may now delete the original image and the "secret" archive and empty your recycle bin to destroy any evidence.

Now, to extract the "secret" out, just open the image file with the archiver you used to archive it.

Tuck this image into your image folder to confuse sneaky hackers or your naughty son to prevent it from accessed or accidentally deleted.

That's it~
Happy hiding. hehe~~~

Defraggler

Windows integrated defragmenter, which usually takes almost forever to defragment a single drive, and you don't even know how's the result... I've been using it, until I discovered a better defragmenter, called Defraggler.



I just defragmented my harddisc recently, so not much fragmented files now. But what good is that you can actually see how your fragmented harddisc looks like, and the process of defragmenting!

I once had 10+ fragments, the Defraggler finish its job in less then 3 hours, and I'm using my computer at the moment, not even a single lag occurred to me. It's like it finish its job without I even knowing about it.


You can download it from here, their official website.
The team that developed this Defraggler are the same team that developed the CCleaner I introduced some time ago.

What's a favicon?
It's a small, cute lil icon represents a website. For exaple:

First of all, create your own favicon with a size of 16 x 16 pixels, with file format of .png or .ico . Inkscape does the job well for making a picture and exports it into .png. You can use AveIconifier 2 to convert it to .ico if you like, but not necessary. (File size may vary)

Once you got your image ready, upload it somewhere, like photobucket or ImageShack.

Go to your website, add these two lines in between the <head> and </head> tags.

<link rel="shortcut icon" href="http://YourImageURL.png" />
<link rel="icon" href="http://YourImageURL.png" />

And...That's it!!!
You've got yourself your own favicon for your own site.
Cheers~
