Hi, From the wiki https://wiki.contextgarden.net/Command/externalfigure: "When the file extension is .auto or method=auto is used, ConTeXt reads the first few bytes of the file to determine the filetype. Such an auto-discovery is useful for remote images that do not have a file extension." current version: 2023.09.26 18:19 Code: % SOT \starttext \startplacefigure \externalfigure[https://placekitten.com/408/287][method=auto] \stopplacefigure \stoptext % EOT Expected: Cute kitten photo. Actual: Error. Is this a regression? Or has the syntax changed (stale wiki)? Specifying the type works (I'd've thought it not necessary to specify the method at all, given both magic headers and HTTP content-type could determine the type): % SOT \starttext \startplacefigure \externalfigure[https://placekitten.com/408/287][method=jpg] \stopplacefigure \stoptext % EOT See also: https://gitlab.com/DaveJarvis/KeenWrite/-/blob/main/src/main/java/com/keenwr... https://gitlab.com/DaveJarvis/KeenWrite/-/blob/main/src/main/java/com/keenwr...
