I had a bmp file in which I hid a txt file. Anybody know why the resulting file is only bigger by 2 bits than the original file? Or at least what the extra bits are?

Thanks

There is generally a lot of redundant data in an image, especially when you are dealing with ? 24-bit RGB images. It will vary depending on the image type, size, etc.

Carlsberg don't run I.T. departments, but if they did they'd probably be more fun.

Perhaps the key? Or it was not possible to fit it all in?

Doesn't hiding a file inside an image generally give you a key/password?
