Downloaded images are low res and it throws an error: "browser_process_sub_thread.cc(217)"

Thanks for this script.

It works, but it downloads low-res images (~1MB) and it throws an error:

[7092:18816:0604/153125.097:ERROR:browser_process_sub_thread.cc(217)] Waited 17 ms for network service

Now the error seems to be from Chrome, but I may be wrong here.

Hey Serge! Not all images have better quality, it might be a case that your image is low res? Can you try with other?

Hey @Boquete,

Thanks for such a prompt reply. I've used another tool to download this image (and others) - Google Art Downloader - and it got me a 10MB image. However, a colleague managed to get an even larger version of that image. Unfortunately I have no idea how he did it.

Anyway, I've tried indeed with other images too, I get a similar error in most cases.

Hey !
For those who are interested, the encryption google uses for the individual tiles composing the images has been reversed, which allowed us to create tools that can download maximum-resolution images without the need for a web browser. See :

• dezoomify : https://ophir.alwaysdata.net/dezoomify/dezoomify.html
• dezoomify-rs : https://github.com/lovasoa/dezoomify-rs
• gapdecoder : https://github.com/gap-decoder/gapdecoder

That's great news!
