the creepy Tom Hanx building photo (JFIF header, and location 0x88 = x32 x32 x32 x32)

Post 2790 flag image "GOD BLESS THE UNITED STATES OF AMERICA _ PREPARE.png" (PNG header, loc 0x88 = xAA x5B xF2 x3B) ... however, I checked the one at qposts.online; it may be worth checking the original.
So we have at least "SI"/"SIS" or ?S?I?/?S?I?S where ? is some other chars.
full output of exiftool ,maybe you notice more unusual chars in output.

The fingerprint of a PixelKnot-encoded image is no JFIF header, and the hex bytes xFF xC0 x00 x11 at location 0x88.
I've checked the following images and did not find this fingerprint:
SpaceForce Commissioning Ceremony (JFIF header, and location 0x88 = x31 x1C x02 x3C)
the GeorgeNews 1-year-delta picture (JFIF header, and location 0x88 = x31 x34 x34 x35)
the creepy Tom Hanx building photo (JFIF header, and location 0x88 = x32 x32 x32 x32)
that creepy Wayfair rug that looks blood-splattered (JFIF header, loc 0x88 = x1E x1E x1E x1E)
Post 2790 flag image "GOD BLESS THE UNITED STATES OF AMERICA _ PREPARE.png" (PNG header, loc 0x88 = xAA x5B xF2 x3B) ... however, I checked the one at qposts.online; it may be worth checking the original.
The example in the PixelUnknot repo does have a PixelKnot message: https://github.com/banona/PixelUnknot/blob/master/Q4example.jpg
... as does the first link from the 8kun research linked above (https://8kun.top/file_dl/68ccb4146da74068a0d8749ac6bd3dab249e1a6d947c8ee106ef5bfdc0c9cf6e.jpeg/1*xv-xqPhM_w3qdIatlg8L9A.jpeg)
Hope this saves Anons time.
oh, and funny side-note about the Space Force image ... it's title in the metadata is misspelled as "COMMISIONING" --> missing an 'S'.
Since misspellings are purposeful, seems like this would be a hint to look at what's missing (but props to the Anon who figured the proof first: https://greatawakening.win/p/12hRZjLZAu/space-force-17--decoded--15-of-1/ )
Also misspelling: author of photos. https://greatawakening.win/p/12hRZjLZAu/space-force-17--decoded--15-of-1/ There is no: "Richard Gonzales", there is: "RIchard Gonzales". Big "i"...
So we have at least "SI"/"SIS" or ?S?I?/?S?I?S where ? is some other chars.
full output of exiftool ,maybe you notice more unusual chars in output.
Also - I have a question why we not follow the way mentioned earlier in: https://greatawakening.win/p/12hRZjLZAu/space-force-17--decoded--15-of-1/
Were my look and u/RageBringer look at that not useful at all ?
