That's cool. I'm considering adding a feature like this for images. So you could just link to vb.lk/red-duck-200x300.png And it would generate (then cache) the image. Could be useful for placeholders, a bit like https://placehold.co/

Could even perhaps generate default favicons at vb.lk/favicon.ico and use the referer header (ie. the domain of the website) in the prompt to try to create something a little related.
