The DU software code has to be able to fetch graphics from a link, and then render them for display.

Sometimes, the URL is so complex that the code can't parse it, or parses part of it, but as with video, it takes code to make it show.

So, there's a request for the admins.

Since Google 💩 invented this format that nobody asked for, they provide software to decode it into something that older apps and web apps like DU code, can deal with.

Near the bottom, there are links to binaries and source code.
I put dwebp into a script so I can convert entire directories of webp files at one command.
