Show HN: Public Domain Image Search

With the increasing prevalence of AI-generated imagery, it's also hard to find what is real.

The public domain has many millions of interesting images, all free to use. Why not try to make them more discoverable. The site uses vector image embeddings to find content 'within' the image, rather than just in captions and titles. Search, for example, 'drawings of ships' and the semantically closest search results will be shown (along with lots of other features). 90k images currently added, aiming for 1 million soon.
