(untitled) lainchan / layer ---------------------------------------------------------------------- Yuki Nagato · 2017-04-29 02:02 I'm curious how visible changes are in the picture and what happen if you use an image which already had a message hidden. So I'm going to try I guess. I could do this in /test/ but maybe someone will be interested. (I also guess there is some article about this somewhere, but I'm too lazy to look it up.) ---------------------------------------------------------------------- Fred Nurk · 2017-04-29 02:03 ---------------------------------------------------------------------- Mentat · 2017-04-29 02:14 ---------------------------------------------------------------------- HELIOS · 2017-04-29 02:16 ---------------------------------------------------------------------- Rick Deckard · 2017-04-29 17:15 stegno thread?

But size as in "information content", and a plain black or white rectangle has basically no information stored (it can be perfectly summed up by its dimensions and its colour). Thus you can't hide a message inside. ---------------------------------------------------------------------- Chan Siu Ming · 2017-07-08 16:51 Neat ---------------------------------------------------------------------- plastic · 2017-07-08 16:57 >>207 really neat ---------------------------------------------------------------------- plastic · 2017-07-08 16:58 ---------------------------------------------------------------------- Faye Valentine · 2019-06-26 14:05 ---------------------------------------------------------------------- Project 2501 · 2019-06-26 18:35 >>41 ---------------------------------------------------------------------- Drano · 2019-06-28 09:54 ??? ---------------------------------------------------------------------- Unspecified · 2019-07-07 14:19 ---------------------------------------------------------------------- Hitomi · 2019-12-03 09:45 >>41 ---------------------------------------------------------------------- Jens Hansen · 2019-12-04 12:14 >>41 yea i spend so much time i cant extract anything anyone has a hint? ---------------------------------------------------------------------- Gyula Kovacs · 2019-12-04 13:27 >>1415 Follow the sticky guide. On firefox you have to enable the greasemonkey userscript per site. (gmonkey / DDT / options / includes) The default broadcast address is 'desu' in each of the 3 fields (danger zone, if you changed it) Reloading and opening a thread (via catalog for ex) helps. ---------------------------------------------------------------------- Arisu Mizuki · 2019-12-04 14:17 >>41 >>1416 ---------------------------------------------------------------------- Tyrell Wellick · 2019-12-06 12:18 ---------------------------------------------------------------------- Masami Eiri · 2019-12-23 21:11 >>1418 > ---------------------------------------------------------------------- Rick Deckard · 2020-01-15 10:18 ---------------------------------------------------------------------- Armitage · 2020-10-30 07:02 ---------------------------------------------------------------------- Yuki Nagato · 2020-11-07 05:29 ---------------------------------------------------------------------- 藤原純一 · 2020-11-10 06:16 how do i do this ---------------------------------------------------------------------- Void · 2023-09-06 01:25 came here to test this for the first time. keeps saying: Your request looks automated; Post discarded. ---------------------------------------------------------------------- Nguoi La · 2023-09-17 23:02 The github says it's a steganography tool but i see nothing about steganography.. ---------------------------------------------------------------------- Leto Atreides I · 2023-11-14 20:03 >>1859 guess it got disabled or something ---------------------------------------------------------------------- Jim Hilger · 2023-11-18 22:24 ---------------------------------------------------------------------- Anamika · 2023-11-21 14:18 I've tried here and other chans, and no dice on getting it to work with and without 4chanx and other scripts running.
