The demo doesn't work for me, I upload the image and then nothing.

Is it a large image? On my iPhone, it took a solid 30 seconds to open a really big, high resolution image from my photo album.

I know this is like uncouth, but could you open it in devtools and show me the output?

I've gotten hundreds of comments from other people on the internet who were able to use it. I would love to help fix whatever this bug is so you can try it out too.

I uploaded a photo and it took around 20 seconds. Maybe a loading indicator would help.

Noted! Also adding predefined color palettes, like monochrome, sepia, etc.

I've found LLMs come up with really good color palettes, too.
