Opt out of Webp images for PMB
mnelson4 opened this issue · comments
When PMB is generating files, we should opt out of webP images because they aren’t supported by Prince CSS, and probably won’t be well-supported by ePub readers, Amazon, MS Word, etc.
Apparently I can use filter wp_content_image_mimes, see https://core.trac.wordpress.org/changeset/53751
webp got blocked by Matt Mullenweg, so I don't think I need to worry about this
