Made a python script (just a prototype, might port it to a faster language) that converts any filetype to PNG.
Now you can share whole floppy disks worth of files through this image board.
This image is an exe that plays silent night
(also, has this been done before?)

It's more to prevent people uploading rar files with cp inside.
>>52039530
Someone had made one called "snowcrash"
>>52039578
So basically if I upload a randomly-generated image and it decodes to a .rar full of CP I'll be banned?
cmd:
Ren executable.exe photograph.png
Yes, this has been made before :D

A few weeks ago we wanted to store files on youtube by creating videos with black and white pixels as bits.
We also uploaded webms here, but mods deleted them because >>52039552.

Yes. Then again, how small are the chances of that actually happening?

You can decode anything to CP with the correct cipher

Yes, I remember there was a time when underage kiddos respected the minimum age requirement and were intimidated by the board.
I did this a while back for no reason. It's the most pointless thing ever. I suppose in some cases it might be actually be useful to visualize how data is arranged throughout a file.

If you do this with an audio binary, then perform various image processing algorithms, then playback the transformed audio, you can get some pretty cool audio effects.

I don't think that bring underage had ever stopped people from coming on 4chan. My friends and I started going on 4chan in 5th grade (2003 fall). I started going on /g/ like late middle school. By the time I was in high school, 4chan was well known by every group, from jocks to theater kids. Alot of my friends went on /r9k/ and /g/. 4chan was widespread

What are you, 13 or something?
So after reading this thread....
I still have no idea what you guys are talking about.
>>52039834
Gives some helpful insight but nope not really.
So how do I go about sending a text file.
Im going to text a friend
Yo what up dog
In wordpad.
How do I convert that into an image?
>>52039936
stfu and gtfo. you're not the majority here yet, this is not a democracy, therefore you don't get to make statements like this.
I'm leaving this thread up because it's a really interesting concept but please refrain from posting images with embedded files
>>52040090
I'm interested too, but getting the process down is difficult at best. I'm not even sure what to search for in Google. I've just been trying different ways to append a test binary to a png and seeing if I can get the original back using that method.
I'm thinking if I can't just cat the file to the png, I might be able to import the original as a 24 bit raw bitmap and append that to another png in GIMP.
>>52040090
Well you could simply convert the plaintext ascii to hex and convert every 3 bytes to a color
>>52040105
sankyuu mod senpai
>>52040090
put files in compressed archive(winrar, 7zip ect) rename to bmp, edit in paint save as png
>>52039530
Can you explain your algorithm? I think your encode/decode functions are a little poorly documented.
>>52040030
In the good ol' days you just married a 9yo.
>>52040105
got it, retr0capez
>>52040090
The basic concept is to take a file and convert it to an image.
Most common image formats support 8-bit RGB, so it's easy to convert a single byte into an RGB component.
So say if you had three bytes:
0x01, 0xB5, 0x46
This would produce the color #01B546, one pixel. Do that for every pixel and you end up with the groovy images as seen in the thread.
>>52040137
Makes sense, but what about the instructions at the top of the file like on >>52039834?
>>52040090
>>52040136
How is this an issue, all you're doing is converting a file to bmp, you literally just take bytes and map them to colors, you can perform any encryption you want on it
>>52039530
Why was the image deleted? It's still in the archive so it's not like it matters.
>>52040204
It's against the rules to post files as images.
>>52040145
blankNum is number of empty pixels at the end, so that the converted file dosn't have lost of 0s appended to the back.
Red channel of first pixel is more significant byte of the number of blankNum.
Green channel of first pixel is less significant byte of the number of blankNum.
2nd pixel stores a 3 letter file extension, one char per each channel.
The rest is 3 bytes of data from the file per pixel
>>52039552
>additional data
but that's not additional
>>52040238
Pretty sure the site detects excess data in uploaded images now anyway.
>>52040238
additional data is any data that is not primarily graphical in nature. I know you're going to debate semantics but that's just how it is.
>>52040246
It does in JPGs, but not PNG. You can't necessarily "hide" information in a PNG like you can with JPG. It's still represented on screen somehow.
>>52040294
Just tried it with a 1x1 png with "THIS IS A TEST" embedded at the end of the file.
Got a "Error: Your image contains an embedded file." message.
Can't you just rename the files from .* to .png or .jpg or .gif or .webm?
>>52040324
If the data is stored as graphical information in the file, it's fine. If it's embedded in a way that it's not represented on screen it won't work. That's why all the effort of converting to RGB and putting it on screen is undertaken.
>>52040361
Oh right, that and >>52040294 makes sense.
>>52040379
If it were any other waycat yourfile >> yourpng
would do the trick.
>>52040498
What does it sound like?
Give me an example of how to run this command properly$ python "IMAGE MAKER - My7p8240.py" "s/anime with long hair.jpg"

no spaces or slashes in the file name!
also enter either e or d not the whole word
OP here. Going to sleep
>>52040673

>>52039530
How does that work exactly?
If I download the png file and then double click on it, is it just a picture, or would i have to convert it back first? I have a vague idea on how to do that, but generally it's boring if you have to do that first.
If it "auto-executes", you could hide viruses and spyware and shit in there which is cool. could send a "picture" to some chick and suddenly have access to her webcam
>>52040800
You run his script to encode binary into a PNG image.
You run the same script to decode one of the PNG images back into binary.
Seriously, just look at the script. It's all pretty straightforward if you know python.
So no, you can't embed an executable and just have it run. You'd have to decode the image into the executable and then run the executable separately.
