Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
If a WEBP image is archived in a ZIP archive,
when opening the image with archive-mode,
the subfile buffer of the WEBP image is opened as a multibyte buffer.
So image-converter fails to display the image.
Sometimes a wrong image is displayed, otherwise the buffer is not
recognized as an image.
Typing 'M-x toggle-enable-multibyte-characters RET' in the subfile
buffer, image-converter works correctly.

Emacs 29 support WebP images natively, so there's no need for
image-converter and the problem doesn't happen.
Patches to have this solved with image-converter when WebP is not
supported natively are welcome.

This bug applys not only to WEBP format, but also other binary image
formats which are supported by image-converter, such as ICO.
