Upload images to w.org CDN for use in the Block Editor block previews

[mapk]

This tickets relates to ​https://github.com/WordPress/gutenberg/pull/17493 about showing examples of blocks in the Block Library Preview. These block previews contain images that need to be hosted somewhere.

What we've tried:

1. Base64 encoding the images was too large.
2. Linking to external sources that were out of our control, like wikipedia, was a concern.

Neither of those options worked, so it's opted to host these images on w.org. Included is a zip of some public domain images pulled from wikipedia. Can we get these added to the w.org CDN for this purpose before WP 5.3 RC1? Thanks!

Optimized JPG versions of these images

@mapk I added some much smaller, optimized, JPG versions of these same images. Please check for compatibility before we commit to using them.

Hi There! can we get these uploaded soon? We'll have to cut the release of Gutenberg shortly (in 4 hours approximatively) in order to be ready for WP 5.3 RC.

Thank you.

@youknowriad 4:30am is not a great time to be asking that question. :)

Nevertheless, images are on the CDN with these URLs.

Oh sorry, @Otto42 I hope I didn't get you out of bed or something.

Thanks a lot ❤️
