We can analyze the PNG file header. Surprisingly, some of it makes sense.

You may try to figure out if the header checksum was stolen from elsewhere and corresponds to another common image size but I cannot be bothered. The data could be subjected to forensic analysis but we only really have 21 unique bytes, the rest is likely nonsense because data encoded by the DEFLATE algorithm is unlikely to be so repetitive. Also, the image in total will likely have just 481 bytes (8+(8+13+4)+(8+420+4)+16), as a less-than-65535-byte IDAT chunk tends to be the last one before a 16-byte trailer. There are very few 300x300 PNGs of such small size we could call memes, most of it will have to be just solid color. Example of a 256x256 map tile you can store in around that size (467 B):

(And this one is pre-optimized, using an indexed palette of just 13 distinct RGB colors as opposed to the full RGBA gamut!)

ZJh (base64) in binary is 011001 001001 100001

You’ve just described every bluecheck on Twitter.

Not joking

Spez is way ahead of you on that one.

I actually wonder what a purely AI/ChatGPT community would look like (no human posts/comments allowed), would they eventually start to develop their own weird culture, memes, inside comment jokes that nobody would even understand? There’d be like a picture of a tire and a rubber ducky with the text reading “Five fingers / garden hose” and all the comments would be things like “The wombat, in ascension, remembers. Nautilus.” Like how fucking weird would they get without human intervention?

Come up for a reply to this quote: “Christ, why even have people anymore? Just have ChatGPT be all the users. It’s already indistinguishable.”

ChatGPT:

While ChatGPT has made remarkable progress, human connection adds depth and emotion that technology alone may struggle to replicate. Let’s appreciate the unique qualities each brings to the table.

I analyzed it in another comment: the header says the image is 300x300px 8-bit RGBA but the data is invalid. Most viewers will notice that and show an error.

However, the syntax it used for embedding images is valid, as data:image/png;base64, is the start of a valid image URL and you can use it like other image URLs in supported Markdown interpretors.

Example, using the 103-byte Google Maps’ sea tiles, and a 178-byte GIF:

![Google Maps sea map tile](data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAQAAAAEAAQMAAABmvDolAAAAA1BMVEW10NBjBBbqAAAAH0lEQVRoge3BAQ0AAADCoPdPbQ43oAAAAAAAAAAAvg0hAAABmmDh1QAAAABJRU5ErkJggg==)
![wink.gif](data:image/gif;base64,R0lGODlhDwAVAKIEAAAAAP//AP//3v///wAAAAAAAAAAAAAAACH/C05FVFNDQVBFMi4wAwEAAAAh+QQFlgAEACwAAAAADwAVAAADSUiq0L2QtEDpg6Bqu/LeAGN5wVRKlVmS6qe17hiDHvlyNciho5N2sxDGtoIMBgyH8Kg4IiMEZ1NKlUarSOdTe81arZHvE3olJAAAIfkEBR4ABAAsCAAEAAQABQAAAwYIGtz+ASQAOw==)

much appreciated!

I’m German and I think I just had a stroke.

If it’s Dall-E, it inserts the words ‘ethnically ambiguous’ into images constantly. I’m not the only one who’s noticed.

https://knowyourmeme.com/memes/events/ethnically-ambiguous-ai-prompt-injection

did it give you the images in base64 from an llm, or from an image generation model ?

It makes sense that they do that since the media and randoms on the internet think everything chatGPT and Bing chat say is as valid as info from OpenAI and MS official spokespersons.

The problem is the model. It was trained on lots of poor quality data. The lobotomy is the consequence of the poor data. If they spent 13 billion on having the data analysed prior to training they could have made their own thing much better.

Thing is, there wasn’t even a chance of having a full Tay incident. The problem with Tay was that it was a learning model, so people could teach it to be more messed up.

Meanwhile, ChatGPT doesn’t learn, and instead has a preset dataset it knows (hence why it only knows things up to September 2021), so the main reason why it got so heavily censored is more likely to avoid much more minor incidents, which imo is dumb.

But can it be decoded into an image?

lol

cool username, btw.

LOL, no kidding right?!

But no, I don’t think that was intentionally designed into the game. They had a unique ‘savegame’ format that didn’t use battery save.

Instead, they used a 48 character table, where each character could be any of 32 different possible characters, where the player was expected to write all this down and re-enter it back in on reload.

But it was checked with some checsum characters at the end(s), making it rather difficult to make a full hack savegame.

Strangely enough though, their own chesksum algorithm 3P5 repeated as such exactly 8 times manages to unlock all 4 characters, max them out, and even defeat the checksum field without even having to bother with it.

So when you next take the SNES LOTR journey, take the power of 3P5 with you…
