how to hide an image in another image in java

By using Steganography we can hide text in an image. But how it works for image.

Anyone please give me solution.

I don't see a fundamental difference between hiding text in an image and hiding an image in an image - except that an image
has a lot more data, so the image to hide it in probably needs to be a lot bigger.

and what did you find when you searched?

"java steganography api" returns about 3.2 million hits.

but fundamentally, isn't it the same problem? "text" is a series of bytes...'A' = 65, 'B' = 66, etc. you hide those bytes in the image.

an image is just a series of bytes, either a series of gray-scale values or triplets of red-blue-green values. surely you could serialize the image into individual byte values, then hide those in your image, extract them, and re-assemble into an image.

I know almost nothing about steganography, but I can't see a fundamental difference here.
