Storing information in an image

[Maqsood Ahmed]

Hello,
Does anyone have any idea that how can I store extra information in an
image. such as text, as a part of image. I don't want to show the text
in an image but I want to store this information in it.
Actual I have to design an application which can embed and retrieve text
messages from an image.
Something like message smuggler (software) does.
Any help in this regard?
TIA
