[Deque]

Hi Solixious.

Thanks for this program. I've had a close look to it via JAD. It hides the characters in regular intervals within pixels. The problem is, that it changes the pixel significantly, so it is visible by the naked eye.

Here is an image demonstrating what I am talking about. You see the dots in the left side:



If I put even more info in these dots become lines:



You can avoid that by changing only the least significant bit of a pixel, which won't be visible for a human at all.
That is still detectable in the histogram though. Avoiding that is harder, but I don't know if people really do steganalysis on a regular basis in oder to find such stuff.

Additionally you can avoid regularity/patterns in the data locations. Use a random generator with the same seed every time or apply some kind of encryption to define the locations the data is stored at.
