I used 5 softwares to find the differences between the two images,and i got them all everythime but i never had the possibility to somehow get some morse encryption from there.Could you tell us how many characters has the pass,to know at least at what lenght of morse code to look?Thanks.

Hi paipai...

Stuck as you are. Just compared the two pictures (I took the first pointed by Google but perhaps is it another one ?).
I got exactly 129499 different pixels between the two picts. And the new one created with that doen't show something really usable, even thinking Morse. I did the same with only r differences, then g and achieve my test with b... Nothing.
If the difference between r,g,b would have been 0 1 or 2, we could have thought of one value for dash, one for dot and one for space... But noway... And btw, one Morse chaos by Phas is enough :)
I definitly know I'm really bad at stegano :(

i have 5 pictures with the same dimensions of the original picture (341x400) but noone have the same size in bytes, i compared all pictures with the original, and i have a lot of differences, too much to get something like morse :(

well, I did a little research and did in python a script that compares every pixel in the 2 images.
And drawing in a Third Image the result (black=pixels don't match, white=same pixels in both images)

this is what i got

cp77fk4r it seems that everyone needs a good hint on this one,it is a easy rated level but it seems no one can pass it except BugTrip and that new guy PheoniX,wich god knows how they did it,since they are online 5 minutes and they solve 20 levels.So as you can see we struggled a lot and we can't get it.At least a link to the original picture.I think this challenge should be removed.Only 2 managed to pass it in so many years since the challenge is up.That's not ok.

I developed a program but i still cant figure something like morse code :S
I notice that the edited pictures isn't really in the size because it in the same "pixels size" as the source pic, but when u see the two picture u see change in the center of the source.

Put your results here, It's quite difficult to understand what are you talking about.
