About this extension
The high-resolution image is displayed in full width.
A small caption gives the title and links to the corresponding Earth Observatory article.

The latest entry information is found with the RSS feed. The high-resolution image url is found by scraping the article page. This is saved to local storage to speed subsequent accesses as much as possible.

Disclaimer: this is amateur code, I barely know what I am doing

Release notes for 2.0
  • Uses EarthObservatory to obtain latest high-resolution image (RSS feed is faster than with VisibleEarth which makes it usable, and high-res image is easier to scrape from article)
  • The title links directly to the EarthObservatory article (instead of the VisibleEarth entry)
  • Use local storage to cache information on latest entry and hopefully speed up homepage loading
