Steganography tool to hide/retrieve text or an image in an image.
Once data is hidden in an image, one can't tell the morphed image from a bunch of others (even similar looking).
Open any image and run Filters>Steganography>Hide to specify an input text file or image[lossless]. This will hide the data within the opened image. You can then save the image as a png/bmp/lossless format.
