LGTM! As with H2O PR, apologies for the slow review.

Now that the logo carousel is gone, we use pillow even less. After this is on stage, I think I will manually test an upload-your-own link of supported and unsupported formats, and a replacement link, just to be extra careful. (Those things are covered in the test suite, but just ot be thorough :-)
