have you tried renaming it as a .zip file and extracting itself?

Install binwalk. If you want to do it manually, learn about file signatures and get a hex editor. Copy and paste the hex and save as a new file.

Can it actually detect this stuff?

>>60515325
The answer is no.

>small resolution picture
Among other checks, the 4chans also compare the image dimensions to the filesize to find embedded content. Tiny images often trigger this, despite not containing anything.

Way back in time there were guides to do exactly what you're asking op. On /b/ and /g/ there were threads dedicated to sharing books. It was cash. Then moot fucked it.

I thought mootle implemented automatic filtering for embedded zip files on pictures. It was supposed to be one of those things to reduce the change of getting FBI'd.

>>60518617
yea, you can just cat an archive to the end of an image anymore
but you can still encode arbitrary files as pixel data in png/gif though, as they're lossless formats

The Ouya has been dead for a good, long while now. If anything, it will serve as hard proof that you can't run a sustainable business on a tip-jar model.

>>60518671
I stand corrected.

I'm aware that Imgur.com will stop allowing adult images since 15th of May. I'm taking actions to backup as much data as possible.
