Not so far ago I elaborated on adding copyright information for images on a Hugo-based website. Through this approach, I managed to learn how to get images per post, then list and use in Schema for Images.
Recently, when I read updated Google image SEO best practices I noticed a section called Use an image sitemap where we read:
“You can provide the URL of images we might not have otherwise discovered by submitting an image sitemap”.
I decided to see how I can implement that into my Hugo website.
