>>2629826Let's say that 4chan searches through the bytes of your file and flags it if it contains the 4 bytes "Rar!" which signify the start of a .rar file. There is a (n-l+1)/2^l chance of finding a string of length l in a binary number of length n, if your file has 1MB, n=8 million, l=32 (4 bytes), so the probability is ~1/537 of finding a false positive. That happened to me before, a png that I had created myself was flagged by 4chan by mistake. If you change one pixel and recompress it, that should do the trick.
You can also find out if there's stuff hidden in an image by unzipping it, just choose the unzip option after right clicking it.
It's most likely a false positive, who knows what sort of code janny has thought up for this stuff, it might just suck ass. Just load it into photoshop/gimp and export it again to be sure.
>>2630090If it doesn't unzip, you don't need to worry, I can't think of a reason why anyone would hide Information in an image that no one would be able to recover, putting malware in images also doesn't really work, pdfs would be a better attack vector. You don't need to worry.
