Skeb no longer returns jpg and png?

[nisehime]

Recently, skeb extractor was downloading webp images instead of jpg/png. Is it change on their side? It looks like they no longer provide these formats, but I need someone to confirm it.

Yeah, that change is on skeb's side. Each image URL now has a fm=webp parameter, which actually does not matter, it seems. You can change the returned format to avif by using image/avif as Accept header, but jpg or png have no effect:

$ gallery-dl -o downloader.http.headers.Accept=image/avif https://skeb.jp/@kanade_cocotte/works/38
/tmp/skeb/kanade_cocotte/38_657194.avif
/tmp/skeb/kanade_cocotte/38_657195.avif
$ gallery-dl -o downloader.http.headers.Accept=image/png https://skeb.jp/@kanade_cocotte/works/38
/tmp/skeb/kanade_cocotte/38_657194.webp
/tmp/skeb/kanade_cocotte/38_657195.webp
$ gallery-dl -o downloader.http.headers.Accept=image/jpeg https://skeb.jp/@kanade_cocotte/works/38

Danbooru also had an issue for this: danbooru/danbooru#5297
