anon has looked at many of the qpost images from a steg perspective. some contain classic steg markers in jpgs. issue is these markers can originate from damn near any program these days, dslr cameras, drm, cloud-based editors, desktop editors, websites, etc… it becomes a little murky with all these false positives. visual inspection with using channel lsb & indexes also hasn't been that useful, though I remember one having a distinct marker in distinct outguess like noise. as for pngs, anon has run most of these through some 1st attempt tools, but mostly got junk.. esp from zsteg. might be worth it to revisit the images with a fresh set of eyes.
