Try refining your search with the term steganography
– Mike Fitzpatrick – 2012-07-27T06:39:18.440You 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 – 2012-07-27T08:12:08.093
without modifying certain extent – BlueBerry - Vignesh4303 – 2012-07-27T08:14:44.717
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.

The answer is that you don’t. You can easily append a file to a picutre without any special tools, but if you want to hide it as well, then you must use special programs. – Synetech – 2012-07-28T13:15:49.933
@Synetech i edited question sir please review it – BlueBerry - Vignesh4303 – 2012-07-28T13:21:18.837
@Synetech i dont know where to begin from please guide me – BlueBerry - Vignesh4303 – 2012-07-28T13:22:44.763
I told you, if you want to really hide it, then you need stego software because Windows does not come with anything that can do what you want. What do you want or need to do? – Synetech – 2012-07-28T17:53:59.063
Let me get this right. You want to do steganography without using steganography tools? I am kind of getting the idea that we are either misunderstanding what you are trying to do or you do not understand the limitations of computer software. If you are wanting you can hide a file "behind" a file using Alternate Data Streams on Windows computers. Please could you explain exactly what you are trying to achieve and what you have tried because at the moment what you are asking for is sounding kind of impossible.
– Mokubai – 2012-07-29T08:47:25.357@Mokubai sir i Try to achieve Manually the work done by software Like Stegomagic,as you mentioned its impossible I mentioned the Articles i refereed to do it, i agree with your link "Alternate data stream link" but if you have time please read this PDF sir martinolivier.com/open/stegoverview.pdf i found it possible – BlueBerry - Vignesh4303 – 2012-07-29T08:56:49.027
Steganography is completely possible, but you've reworded your title to exclude using those kinds of tools. Are you now wanting to learn how to do it yourself (in which case teaching you is outside the remit of this site) or are you wanting to do something completely different? If you want to discuss this rather than bash a comment thread and work out how or if we can help you I suggest checking out our chat room.
