To the anon arguing the the big photos just aren't compressed, that may be the best clue!

 

>A common tool against steganography is compression. The basic premise of lossy compression (as is used for media files, e.g. MP3 or JPG) is that irrelevant details can be removed from the file, where "irrelevant" means "does not alter the perceived meaning of the data". Random noise will be tracked and removed by compression. Therefore, compression tends to be at odds with steganography. If you write a filter which automatically recompresses (aggressively) all pictures sent by email, then you will not detect steganography, but you will have made it much harder. In that sense, steganography shares some characteristics with watermarking.

Please forgive me if formatting sucks. I don't usually cut and paste.

>PNG is actually a (typically) lossless bitmap format, ideal for steganography

 

MOST but not all Q photos are PNG.

In so far over my head.

I could do the steps if I knew what was used.

Can't for the life of me figure out all the variables.

 

We'll know, anons, if we are supposed to keep digging on data embedded in images. Last time I made a big attempt, several images magically appeared.

 

(Need a sobbing, humiliated pepe for this one. No such pepe in the growing library.)

My favorite porn.

Do you know that bubbles magically congeal at the single most efficient place? Cells are bubbles. We're just used to seeing them in 2d.

So when a tree grows, it grows efficiently.

When the basalt columns form, it's the most efficient way they can form.

Makes me wonder if this "efficient" technology is what the ancients used for so much of the super-structure building.
