A bitcoin logo on block 123573 (2011-05-13).
This is the very first ASCII string to show up at github.com/cirosantilli/bitcoin-inscription-indexer after only the Genesis block message.
This version of the image was just ripped from Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014).
Reconstructing it should likely be a simple matter of copy pasting the ASCII yEnc encoding present in the two transactions from tx ceb1a7fb57ef8b75ac59b56dd859d5cb3ab5c31168aa55eb3819cd5ddbd3d806 into a text file and decoding the yEnc, but after searching for 20 minutes Ciro couldn't find a working yEnc decoder on Ubuntu 21.10. How can a format be so dead, even after considerable extensive use in the Usenet??? It makes you think about life.
As mentioned by Ken, the logo is split across two transactions: ceb1a7fb57ef8b75ac59b56dd859d5cb3ab5c31168aa55eb3819cd5ddbd3d806 and 9173744691ac25f3cd94f35d4fc0e0a2b9d1ab17b4fe562acc07660552f95518.
There appears to be nothing strictly linking the two transactions, besides that they are very close by and the only ASCII strings around back in those pre-infinite-spam days, as can be seen at: github.com/cirosantilli/bitcoin-inscription-indexer/blob/master/data/out/0123.txt#L11, so you could just see both of them by eye.
Also the first one starts with:
=ybegin line=128 size=8776 name=bitcoin.jpg
and the second one ends in:
=yend size=8776 crc32=a7ac8449
so this is likely clearly part of the yEnc format for someone who knows it, and the filename bitcoin.jpg gives the file format.
They are not even in the same block:
both from 2011-05-13. Also note that they ended up being committed reverse order, since you don't have a strict order control over the final blockchain.

An image of a dozen people siting at a dinner table, with each person identified by a Twitter handle that was edited in.
This image is present tx 4be3a833ee83b4ca7d157d60fbf7411f7528314ce90df8a844f855118bc6ca11 from block 357239 (2015-05-20), an input transaction.
It contains a base 64 encoded image:

By manually copy pasting that into a file v27sSra.base64 we can obtain the image with:
base64 -d <v27sSra.base64 >v27sSra.jpg
The exact same content appears to be present on the next input transaction 56d23a230042c094bc54bb72fc4c10a3f26750030b9927994e741d3689f5c09e on the same block.
Google reverse image search leads to freedom-to-tinker.com/2015/05/21/the-story-behind-the-picture-of-nick-szabo-with-other-bitcoin-researchers-and-developers/ The story behind the picture of Nick Szabo with other Bitcoin researchers and developers by Arvind Narayanan (2015), in which Arvind (@random_walker) who attended the meeting clearly lists all names and handles, and talks about the background of gathering of Bitcoin devs that happened in March 2014. The article also contains a higher resolution version of the image uploaded to the blockchain.
It also links to a popular Reddit thread that contains the image from May 2015: www.reddit.com/r/Bitcoin/comments/36hfu4/pic_coredevs_having_dinner_with_nick_szabo/
Googling v27sSra.jpg leads to bitcointalk.org/index.php?topic=1061926.220;wap "New York Times identifies Nick Szabo as Satoshi Nakamoto" which links to i.imgur.com/v27sSra.jpg so this is a Satoshi Nakamoto-real-identity thing.

Raw images Updated 2024-12-15 +Created 1970-01-01

In this section contains a list of images we could find that wre uploaded as raw data to the blockchain, without any special encoding, e.g. as done by the AtomSea & EMBII system.
It is possible that some/most of those were uploaded via the cryptograffiti.info system, but since that indexer stopped working, and since the format is so non-specific, it is not possible be sure as far as we can tell.
These images were indexed by looking for standard transaction output script hashes that contain JPEG or PNG images immediately on the first payload byte based on file signature bytes and indexed/easily downloaded at github.com/cirosantilli/bitcoin-inscription-indexer#image-indexing-and-download.

This ad highlights one of the claimed potential advantages of Bitcoin: cheaper/faster cross border transactions.
This inscription is highlighted at Data Insertion in Bitcoin's Blockchain by Andrew Sward, Vecna OP_0 and Forrest Stonedahl. Finding Gzips with binwalk is hard because the file signature is only 2 bytes long (1F 8B), so there are lots of false positives.

western-union-bitcoin-spoof.jpg.gz: decompression OK, trailing garbage ignored
but we were not able to fix that: removing bytes at the end goes straight from "trailing garbage" to "incomplete file" after a certain byte.

The image data is cut in half. This makes the image an invalid JPEG, but ImageMagick is able to recover and convert to a valid image which is what we show here to make it portable to more browsers. The raw invalid image is present at: raw.githubusercontent.com/cirosantilli/media/master/bitcoin-inscription-indexer/data/bin/b673c7d0c62cce8315ad6cc63a2c8ca8169bf73432435760b808735e1a7fe0e2.jpg, but it can also be generally viewed by most viewers.

The first block is:
Hello world! Return blob protocol v1: MAGIC = 0x62, PACKAGE = uint16, SEQUENCE = uint16, PAYLOAD = up to
which then gets repeated, probably an error, but now with the sentence completed:
Hello world! Return blob protocol v1: MAGIC = 0x62, PACKAGE = uint16, SEQUENCE = uint16, PAYLOAD = up to 35 bytes
This therefore gives us the name of the protocol as "return blob protocol". We also understand that the 0x62 was aconfiguration parameter.
ffd8ffe1 marks the start of the JPEG.
If the rest of the image were inscribed somewhere random in the blockchain, we'd expect to find the string 6200010089 containing the netxt data chunck on a nearby block, but bgrep did not find it, so perhaps the data just isn't there.
The last tx of the daisy is 43b182065ab2c7d1908ec3cee756d9f626c1e4bd1efa17a7c3993433b653d499 which is followed by 9e6838a3545bd59a708d0c177d6840c7d82b8ac6220138ca3d8133a1376405aa which does not contain any data.

Chinese wedding

A white man and a Chinese woman wearing Chinese traditional dressess holding hands, presumably a token from their wedding. A Chinese poem is visible next to them, with four vertical setences made up of 7 characters each, to be read from right to left. This is a classic Classical Chinese poetry form known as qijue.
A photo of a snowy mountain is shown in the background, fitting the theme of the poem. It looks like an European mountain, possibly Mont Blanc? TODO identify. Perhaps a reference to the nationality of the husband.
TODO transcribe the Chinese text, cursive grass script + traditional characters + ultra-low res put this beyond Ciro Santilli's capabilities/patience ratio. Ciro Santilli's wife's transcribed gave the first column as:
丹珍默然藏山中
A scarlet gemstone hides quietly in the midst of the mountains.
and no Google hits, so maybe an original poem? What a hero. TODO transcribe the rest.

Fame and fortune become like drifting clouds
But the gem endures like the constellations above.

Wedding contract written in Czech. Transcription and translation by Petr Kadlec:
Svým podpisem pod tímto textem potvrzuji, že Daniela Dudysová a Pavel Urbaczka v mé přítomnosti dne 20.8.2016 v Ropici projevili vůli uzavřít spolu manželství, přičemž ani jeden z těchto projevů se mi nejevil jako nesvobodný, nikoliv vážný, nesrozumitelný, omylný nebo uzavřený v tísni.
Translation:
With my signature under this text, I confirm Daniela Dudysová and Pavel Urbaczka have, in my presence on 2016-08-20 in Ropice, expressed the will to enter marriage, whereas neither of their expressions seemed to me to be non-free, not serious, in error, or under distress.
Signatures:
Tereza (unreadable) Hana (unreadable) Jakub (unreadable) Radim Kozub (unreadable) (unreadable) Lenka (unreadable)
Petr also conjectures that Jakub may refer to Jakub Olšina from Blockchain Legal. Figure 23. "Wedding on grass" on the same block contains a image of a wedding, presumably the same of the contract. The photo of the man might be the same person as www.linkedin.com/in/olsinajakub/, but a bit younger.

Entre tus brazos y los míos
no hay espacio, tan juntitos
estamos que los pensamientos
son uno.
A veces somos casi dos desconocidos,
raros tan raros cómo distintos,
pero nos engañamos, tú lo sabes yo lo sé,
en realidad somos muy dentro
la misma verdad.
Escondidos en tus ojitos
duermen mis sueños más hermosos,
cuándo los abres frente a mi
se despiertan alegres y rumbosos.
Which translates as:
Between your arms and mine
there is no space, so close together
we are the thoughts
They are one.
Sometimes we are almost two strangers,
strange as strange as they are different,
but we deceive ourselves, you know it, I know it,
actually we are very inside
the same truth.
Hidden in your eyes
my most beautiful dreams sleep,
when do you open them in front of me
They wake up happy and cheerful.
Not easy Google hits so possibly novel.

This transaction is given at Data Insertion in Bitcoin's Blockchain by Andrew Sward, Vecna OP_0 and Forrest Stonedahl. We've decoded it with:
btc getrawtransaction 94e319d09fc236fb9d7a24e60af8f47ed41ca3cc01e9950c925d806153ed8aa3 true | jq -r '.vin[].scriptSig.asm' | sed -r 's/^[^ ]+ //' | sed -r 's/ [^ ]+$//' | tr -d '\n'  | xxd -r -p > tmp.jpg
TODO understand the encoding better. Our indexing scripts Bitcoin Inscription Indexer missed it because the image is encoded on starting on the second constant of the input script and not the first.
This was missed by binwalk because it does not index the valid JPEG signature "ffd8ffdb"... we should patch it... github.com/ReFirmLabs/binwalk/blob/cddfede795971045d99422bd7a9676c8803ec5ee/src/binwalk/magic/images#L107

This P2FMS has the peculiarity that each payload constant is preceded by a 04 byte which must be thrown away, we've decoded it manually with:
bitcoin-core.cli getrawtransaction 3110f49fb6047d62e6fa198a0a4b180d9abf7075d6f29472747990ae286295cb true | jq -r '.vout[].scriptPubKey.asm' | head -n-2 | sed -r 's/^....//;s/ 3 .*//' | tr -d ' \n' | xxd -r -p  > tmp.jpg

The payload starts with: 7b260000 before the acutal GIF, which is why we hadn't found it before using binwalk. TODO what do those bytes mean?
The last payload uses OP_RETURN and encodes the ascii filename:

How To Build A Quantum Computer by Lukas's Lab (2023)
Source.
Super quick overview of the main types of quantum computer physical implementations, so doesn't any much to a quick Google.
He says he's going to make a series about it, so then something useful might actually come out. The first one was: Video "How to Turn Superconductors Into A Quantum Computer by Lukas's Lab (2023)", but it is still too basic.
The author's full name is Lukas Baker, www.linkedin.com/in/lukasbaker1331/, found with Google reverse image search, even though the LinkedIn image is very slightly different from the YouTube one.
As of 2023 he was a PhD student at NYU.
