I think I have every Q image in original compression.

The thing is - they read one size, and then a different when downloaded.

Anyone know 8ch well enough to understand that phenomenon?

Also, will commit to this location for a week, avoiding the distractions of the main board as much as possible.

ANON NEEDS HELP

Working with an above average IQ and 20 years of photo experience including website design and various compressions, but still in over my head.

Here's the original image - in my best knowledge - for the file discovered by helper anon.

This was the G7 trip where the missile was launched, remember? I'd presume the other file info is the time stamp.

It's going to be a bear to get you up to my speed, but stick with me. Will be glad to carefully convey my trials and errors. Have tried to document them well in my files over the months. Will confess that anon is not working on the best machine for this work. Alternate work in another location, but can't get to it for a while. Hopefully, we'll duplicate that work well enough to make it of no consequence.

First concern: some of these results might be computer/platform/compression algorithm specific. We need to find it, and then we need to duplicate it.

Next concern: this work has been shilled so heavily over the months - even to the point of being removed by a bad BV back in the day - that there will be holes in being able to duplicate some of it. But I bet we can. And we are hopefully oldfag enough to ignore the shills.

>>3276 Believe it or not, anon, this is my weakness. So glad to have you here.

(And crazy to be using such low post numbers!)

We can do this.

Anon is available, available, available, but is fond of sleep. (Currently well rested. Needed that nap.)

Go time.

Ready?

So HexAnon:

Compress the image from 3277 in a zip

Open that zip in your favorite text editor

Search for the words "zip"

Open compressed data in hex editor

Copy the ZIP components

(This is where anon got lost.

Between the words? Zip at the end. Have no idea what Hex looks like. Raised geeks, but never properly converted myself.)

Copy the data re: zip

Try to read it? Decompress it? Edit that string again? This is where help is required.

It seems that was where helper anon was leading us. Did not convey zip program, etc., but something was able to read through the compressed and embedded data.

(Also suspect that kids to raise routine was a cover.)

Billed as full-sized images.

My current thinking is that there are at least two methods.

1) The original images that Q drops with black headers and footers have zip files embedded. The black provides ample room to hide the data.

2) The other drops - without black - might have layers that can be detected using some of the first methods described in that video.

IMAGE SIZE is important. The black-bordered images that Q uses are generally very large, much larger than is necessary to convey a photo to this board.
