Yes it is the whole purpose of steganography
But you might need a vary large image or a sery of image
"Hey John, here are my last vacation pictures. Look at them attached to this mail"

@pbl: that was cool:bigsmile:
but sounds, somebody is in danger...
me.
Last week I've spent in trying to embed a file using this algo !
i was unsuccessful.
i desperately need help !
Is there any other procedure, because using "sery of image" is a bit complicated !

What are the size of both your images ?
Assuming you can hide 1 bit in every byte of your original image you will need an original image at least 8 times larger than the one to hide
But in real life, assuming the Alpha byte cannot be used, you will able to hide 3 bits on the hidden image in 4 bytes of the original one, that is more than 8 times.

22 bytes ???
Sure it will fit in your image file. You can even just use the least significant bit of GREEN (bit 8 of every ARGB)
