Thanks for this script.

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

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 :

That's great news!
