Carl Sagen example image is downloaded with a PNG extension but source is JPEG
The relevant source file for the "carl"
entry (L24) uses an imgur URL that, while suffixed with .png
actually returns a JPEG file. https://i.imgur.com/flTHWFD.jpg
is a valid URL whose resulting download is the same file, if you'd like to have a URL that makes sense to go along with reality.
