- Tharkun 7y agoYou could try uploading a bunch of images and downloading them again, finding out where they differ. This should be reasonably straightforward. However, FB likely modifies the image in various ways (resizing, maybe they recompress the image to save space, etc). Showing the presence or absence of steganography will probably require a large sample size.
