it is possible to use the Carousel feature of the Bootstrap Wrapper plugin with images stored on a Synology NAS instead of uploading them to the DokuWiki again? DokuWiki is also installed on the Synology NAS.
Example of the Carousel feature: https://www.lotar.altervista.org/wiki/wiki/plugin/bootswrapper/carousel
Path of the images: \Synology\pictures\2020-07-10 Tour de Murg
Path of the Dokuwiki: \Synology\web\dokuwiki
