Try refining your search with the term steganography –  Mike Fitzpatrick Jul 27 '12 at 6:39
    
You cannot do this without changing the image data in some way, if you want to embed data in the image and retain the same size then you will have to reduce the image quality. Your note of "without modifying the size of an image" is an impossible requirement and as such I am voting to close. –  Mokubai Jul 27 '12 at 8:12

Fair enough, that seems more reasonable. Have you already found some tools that do the job? Steganography tools as suggested by Mike do exist, have you tried any and found them lacking in features? Lifehacker has a neat guide on tools that do this. –  Mokubai Jul 27 '12 at 8:27

Try StegoMagic! This software can be used to hide text files inside image file, and you can also hide any file into any file. By the way in the field of encryption software, I like Truecrypt the most, it's free and powerful. I recommend you to try it. I hope this will help you!

Hiding data inside inside an image is done by using steganography, this method can be used to hide data inside other files types too for example mp3 and video to name a few.

I can't recommend any particular software but a quick web search finds this free windows tool QuickStego. It shouldn't be hard for you to find more if this doesn't fit your needs.

Be aware of it's limitations though.
Steganography just hides the data and unless you also encrypt it it can be extracted by tools such as Stegdetect.

You can read more about steganography and ask questions about it over on security.stackexchange.com

Yes it is possible. But I don't really get why you would go through such trouble as there are really good encryption programs out there.

i like to mention that post was related to merging and it doesn't mean to hide, –  BlueBerry - vignesh4303 Jul 27 '12 at 6:34
    
The command just merges the folders into the picture,i guess merging is different from hiding. –  BlueBerry - vignesh4303 Jul 27 '12 at 6:50
    
@wbeard52 I have seen this method once, and i have use it before. But Main Problem is i don't know how to unbind the file. Could u help me? –  Titan Zack Jul 27 '12 at 9:29
    
The point of encryption is to conceal the content of a message. The point of stenography is to conceal the existence of a message. One won't do when you need the other. –  Michael Kjörling Jul 27 '12 at 9:48
    
@Titan Zach Try WinRAR to view the contents of the two files. –  wbeard52 Jul 27 '12 at 18:04
