Show HN: Create a QR code with text in the code pattern

Just a note, instead of encoding the picture in the full destination URL, you can encode the picture into the padding section between the URL and the Reed-Solomon section, thus permitting the use of any URL.

I used this technique a long time ago on qrpixel.com but forgot to renew the domain, oops...

Also for information about how this works, Russ Cox did a good article on it, calculating using the R-S section as well: https://research.swtch.com/qart

I used qrpixel to draw my avatar https://avatars0.githubusercontent.com/u/714648?s=460&u=2bca...

I'd be very glad to see it online again.

Can you deploy it somewhere? It seems very useful. Netlify should work great if it's a static page.

Wow, I really like what qrpixel did! Do you know of any alternative tools (that are still around) that work the same way?
