So it just writes your message to the first bytes of the image? Sounds like it will mess up the "magic number" that most programs use to determine file format, making your jpeg look corrupted and highly suspicious."

like this"

It will append his bytes to the end of the file. Not sure if that will fuck it up."

"Simple way or hard way?

Simple way is make sure you start with jpeg/jiff file format.
Exif data has a comment section. Some photographers use this to add captions to their images. When you look at the photo you do not see the message or any of the other information contained in exif
If using a window box, right click on a jpg, go to properties/details

Bad news, anyone who knows how to right click or anyone who has a exif viewer can see your comment."

if(Anonymous && title=="" && postNumber==1491412 && dateTime=="11/03/18(Sat)22:34:58")

Hard way?
Start with any image of your choice.
Use windows
Probably good to start with a file larger than 1024 bytes so the file is non resident.
Open the file with the hex editor of your choice.
Wright whatever you want in the file slack
Most people will conduct key word searches in ascii so consider writing your message in Unicode
Without doing the math, you could hide and 3000 bytes with this method"

"why would you want to try and hide a message?
what you're trying to do is hide or find CP nigger"

if(Anonymous && title=="" && postNumber==1491420 && dateTime=="11/03/18(Sat)22:54:55")

Spy tier way?
Again, assuming window NTFS formatted drive.
Use a file that is 1024 or larger so the data is non resident in the master file table.
Use your hex editor and find the image file entry in the master file table
Change the run list to add previously unallocated clusters to your file, you can add as may clusters as you need,
To make it harder use a fragmented file instead of a contiguous file
Change the Last Virtual cluster numbers to match the new value depending on how many clusters you have added
Change the allocation status of the additional clusters you added from unallocated to allocated."

Why would you hide a message in CP?"

Starting from the image data offset, programmatically replace the LSB of each byte with a bit from your message, the image will look unaltered to the naked eye as long as its not a solid color or anything"

"Almost all these methods don't work on 4chan. Moot had to do away with them because >>1490303. There are only two ways that still work, and "work" is relative.
>Method one: Embed a file into a PNG.
PNG, being lossless, can store raw binary data in itself. I'm not sure how to do make these. The data's there, but it can't be hidden."

if(Anonymous && title=="" && postNumber==1493006 && dateTime=="11/06/18(Tue)20:38:51" && image=="spoopy.png")

">Method two: Transparency
Real simple. Make your image, add an alpha channel, make all the pixels transparent but keep the color value for the transparent pixels. GIMP can do this, not sure about other software. It's good for "censored" images that any clever anon can uncensor at their leisure."

if(Anonymous && title=="" && postNumber==1494160 && dateTime=="11/09/18(Fri)04:40:14")

Not the same guy.

You're retarded. Don't talk about shit you have no idea about. Protip: extension doesn't mean jack shit. It's only used to help your OS know which program to use for opening the file. The actual program determines how to decode the file using the first few bytes of the file (AKA the magic byte). You can have a jpg with an extension .faggot and if you open it with an image viewer, it will know its a jpg image by te magic byte"
