That program calculates the average LSB (Least Significant Bit) of each block in an image. It's a method of detecting changes to images imperceptible to the human eye. The slightest changes to the visual image result in noticeable shifts in the graph. Top is the analysis of the original flag Q posted 2017 11 12, bottom is today. Showing that while the file sizes are different, the image itself is identical.

Quite relaxed, thanks. Just quashing the debate I know shills will try to spam for days.

Filenames are irrelevant and both files have no EXIF data.

So get thisโ€ฆ the SHA256 hash of the original (2017 11 12) is the 8chan generated name for today's. Which implies it was the same image uploaded. I think 8chan had to have increased the compression after upload (PNG is lossless) - how else could that happen?
