JPEG image of Shakespeare which is also a zip file containing his complete works
In the years since I posted that, twitter has changed some of their image processing pipeline, so that precise technique no longer works if you want to upload new files (last time I checked - and I didn't investigate further or look for workarounds).
However, it's much easier to embed data into PNGs, and the best twitter-compatible implementation of this I'm aware of can be found here: https://github.com/CleasbyCode/pdvzip

I found a software on Twitter that allows you to store up to 3MB into a PNG file. The source code is included.
This was made by David Buchanan on Twitter. He explains more in his Twitter post and on Github. It seems like a really cool idea to incorporate into a puzzle, so I figured you guys would like it.

Security Researcher Hides ZIP, MP3 Files Inside PNG Files on Twitter
A security researcher has discovered a novel steganography technique for hiding data inside a Portable Network Graphics (.PNG) image file posted on Twitter, a tactic that could be exploited by threat actors to hide malicious activity. Researcher David Buchanan heralded his discovery on Twitter earlier this week, accompanied by a photo declaring: “Save this image and change the extension to .zip!” He made the source code for his method available in a ZIP/PNG file attached to the image as well as on a post on GitHub that explains his methodology.
