This might mean your libwebp-7.dll is incompatible with Emacs you have
(e.g., it's a 32-bit DLL, not 64-bit DLL), or Emacs cannot load it for
some other reason.

Corwin, can you please verify that the binary on the GNU FTP site can
display WebP images when a suitable libwebp DLL is available?  The
Emacs 29.1 I built myself here is definitely capable of displaying
WebP images.
