So, do you now run pixelknot on the images to retrieve the embedded text?
Pixelknot is available for Windows only. I have a Mac. Someone who uses windows will have to download the software (free). If you can post some of the pics that you identified as having the Pixelknot header, then another anon can run the image through Pixelknot. The PW to decipher may be in the header for each image. Anyone with Windows want to step up and assist?
You can go to guardian project or google play and download the app. It is for android only. I have IOS.
Let us know the results. The Pixelknot app is for Android only (Guardian project or google play) I have IOS devices. Someone with android, please step up and assist anon.
Now, use another steg detect software and compare output results for false negatives from stegdetect.
Preferably an app that uses F5 algorithm like Pixelknot
