how could i we possibly know that most digits that start with 0 are unreadable...
its like i should have guessed that?
and i STUDY this crap.
this should have been a hint...

To me that was a very nice puzzle, and rather not a complicated one, too. Can't see why so few entrants. It made sense - negated image is negated bits. Also, 8th bit equal to 1 = upper ASCII = garbage usually. Also, 0xDF
is rather clearly inverted 0x20
i.e. space.
I have to admit that I myself tried first only the positive images, but that didn't make much sense, so I took a look at the negative ones as well and it made sense right away.
I didn't find the comments in the pictures though, I guess I didn't learn from my own puzzles that bit of paranoia can lead to surprises xD
Thank you, zolwiciel, for this puzzle, and as well huge thanks for the actual gift <3

... true or false. 0 or 1 - simple as that
9c 90 64 9a 3a df 74 4c 8b ab 36
Edit: Only 2 entries. But there is nothing more to add - the general idea is in your comments below. The more you search - the more irrivalent info you are geting.
Start with trying to solve the cypher without even clicking on those links.
Edit2: there are 4 entries and less than 7 hours to go. I'm not gong to post an more hints as it IS really simple. All i used to make it was notepad, graphical program to invert colors, this page and as you can see dropbox to store files ;)
Almost last call 38min left - giveaway ends 7:40pm GMT
SOLUTION:
1) The message is in a hex code - i think everybody guessed that
2) everything can be only 0 or 1 - his mean that the most of the time you will nedd to look at the binary code
3) simple hex decoding would give you something like ��d�:ßtL�«6
4) 4 of those chars are alphanumeric the coresponding images were the original ones, there was also this ":" - will get to it later
5) the other images have inverted colors - why did i did it if (as some of you checked) there was nothing helpful under those images. thats becouse i didnt invert just those images, ive simply inverted the "numbers" - thats why it gives you something that is unreadable (most of readable chars have 0 on the front - the inverted ones had 1 - if someone knew binary well he could tell hat somethings wrong with those char just by looking at the code, also people were posting here the order of the pictures in binary - 11010100101 - those are also the first digits of the binary codes ;) )
6) how to "invert numbers"? - simple, if you remeber you are working on binary code - just change the all 0s with 1s and 1s with 0s
7) now put it all in the binary translator (the ":" shouldnt be inverted as it pointed to an original white image, but it didnt really matter what you did with it)
6) now we are getting "code: tLtT6"
Some people got it on time - Gratz to them as well to those who found my comments in under the pictures
