hdnimg - hidden in plain sight

this is a small tool for adding bytes in images by changing the least significant bit, which will not change the appearance of the image

• the bit count can be manually changed, but be careful setting the bit_count to 8 (the max) cause this will effectively make the tool replace the image pixels.

Example

source image	altered image

• Notice how these images look identical to the naked eye, yet they are different on a bit basis.
