Last year, there were several publications in press that al-Qaeda operatives were sending out encrypted messages to the terrorist groups members by hiding them inside digital photographs on eBay. While there no definite proof that this claim is justified, it is quite easy to hide any other file or group of files inside a JPEG image. You can place video clips, pdf, mp3, Office documents, zipped files, webpage or any other file format without special software and encoding knowledge. Any stranger that will get the image and will open it in either a photo editing software or as a thumbnail inside Windows Explorer, there will be no visible indication that the open file is more than just a regular image.
Let’s learn this simple trick, available with tools embedded in Operating System.
Step 1: Choose the secret file or groups of files, you want to embed in the image. For multiple files, compress them in a single archive with locking password if needed additional level of the data security.
Step 2: Select any image JPG file, where your data will be hidden.
Step 3: For simplifying the application, move the two files (data file and image file) directly on the root of your main drive C:
Step 4: Open Command Prompt (Start - All Programs - Accessories - Command Prompt).
Step 5: Type in the DOS-like window “cd \” to get to the drive, where the files moved on the step 3.
Step 6: Type “copy /B original.jpg + secretfiles.zip new.jpg”, where “original.jpg” represents the image file, you are planning to use as your data safe, “secretfiles.zip” (or any other data, video, audio, or text file) is the archive or file you are going to hide, and new image file with hidden information “new.jpg”. The “/B” stands for binary, just for your information. By adding this mark, you copy the secret data in binary mode onto the end of the new JPG image. When the picture is opened, the JPG header says the length of the data and ignores everything below (the hidden data). So, the only difference between the original and the new image files will be in the file size.
The new file with secretly attached information is ready to be sent or stored for future use. Recovering the original data is pretty easy. If inside is archive (ZIP), rename the new image from extension JPG to extension ZIP, and open with any compatible archiving program. If your file is TXT, you can rename it to text format or just open the “new.jpg” file with text editor.

"Your Password or Username is Invalid. Please Try Again."
“Sorry, the member name and password you entered do not match. Please try again.”
“Invalid ID or password.”
I bet, you have seen these and other similar error messages multiple times. You try again and again, and the stupid server does not want to recognize you. How frustrating and depressing! In some cases, the problem is real, and is caused by the mess in the service database, or by the server being completely down. There is nothing you can do in this cases, but patiently wait until it will be up again. But, sometimes, the problem is on our side and its resolution is within our troubleshooting capabilities. Several recommendations for the case investigation are presented below:
- Make sure that you are using the correct login information. If you have multiple online accounts, you might forget the correct one for this particular site. It is recommended to use password manager for logins preservation (as browser built-in, as third party like Roboform).
- Verify that your CAPS LOCK key is OFF as, in most cases, login information is case sensitive. In many keyboards, there is the monitoring led, showing the status of the CAPS LOCK key. Please, put attention that the it is disabled.
- Do not copy and paste your password or username into the text boxes again and again. Stop, and type it manually.
- Retype your login information, carefully proofreading all the data inputted. The most common mistakes are related to use of the dot key instead of comma key, or neighboring letters accidental substitution on the keyboard.
- Use your mouse cursor to move from one login field to another, instead of using the Tab key. This way, you can better control the proper information filling as per site requirements.
- Avoid hitting the Submit or Log In buttons more than once with your mouse. While using keyboard, hit Enter key just once as well.
- Wait patiently until your login is properly completed, before you do anything else on your computer. I know that the computer operator is usually multi-tasking. he will rush forward, with no particular patience to wait for the login completion. It is fine for you, when it is fine. But, in most cases, when you badly need to login, and you can’t, you will be ready to do whatever needed to get in and show any degree of the patience needed. So, after hitting the login request, do not touch anything on the keyboard, do not touch or move your mouse, do not switch to another screen, window, or program, and do not open any new applications.
- Do not connect any external hardware devices and do not insert DVD or Floppy, while in the process of logging in. Do not use your RAM for side operations.
- Nothing helps - close all browser windows, and restart the browser.
- Security settings of your browser might be too tight to enable your login. Set your browser security to its default settings and try again.
- If cookies, for some reason, have not been properly accepted, you might have problem of being logged out of your account as soon as you move to a different page, or you might be completely unable to login. Delete your cookies: close all browser windows, find the "cookies" directory, and delete the cookie files inside. Or, use any of the special software to clean cookies safely.
- In some cases, you might need to clear your browser’s cache to refresh the content of the recently visited web pages.
- And the last generic recommendation: perform the “cold” computer reboot. Shut down your computer, wait for 5 minutes, and turn it back again.
- If the problem persists, for further investigation, you can try to login to your account using a different browser, or from another computer. At least, you will be clear if the problem is server or your personal account related, or it can be linked to your computer and settings. Remember also, that in some servers there is a limited amount of attempts you can make entering incorrect login. You will not be able to login, if the you try to input the correct login after that for safety reasons. Call to the company tech support and clear the issue.

First of all, why should hosting companies offer free web space at all? In many cases, your page, indeed, includes host plugged advertising or banner. Here, the free host’s motivation is clear: your site exposure will bring some passive income. But, recently appeared many hosts that do not include their own ads at all on the sites they are giving away. I contacted one of the owners and asked why? He responded that he has an excess of the available hosting space, and he is giving it away in hope, that some of his free account guests will eventually move to the paid web hosting with additional features, unavailable for the complimentary accounts. This is also a valid motivation, but it is not in any conflict of interests with a free account owner or with free Web site visitors. If this Web site is unreliable, a free account owner will just migrate to another host without hesitation. There is a strong competition even among free, ads-free web sites on the market. Definitely, for serious online entrepreneurs, paid hosting would be a better solution. But, for newbies or for not much profit-oriented people, it may fill completely the hosting needs. Better to have any web presence, than no presence at all. And, associated costs keep many interested Internet users from getting their own Web Home.
I have created a Rating List, featuring more than 100 Best Free Hosting Opportunities on the online market. There are many hosts offering Web Space, so, I have no intentions to cover them all. The main requirements that impact on the host’s rating are the following:
- The free host should not require you to use your own domain name, or to register a new domain name as a condition to give away free space.
- Offer should not be neither temporary, not time-limited trial.
- Preference for hosts with no forced ads.
- Preference for hosts, allowing using your own ads (like Google AdSense) on your page.
- Preference for hosts, allowing FTP site loading.
- Preference for hosts, offering nice and short sub-domains.
- Any other extras are a plus. For example, ability to earn for spreading a word about free ads-free hosting 000WebHost is a definite potential advantage.
