I thought it was necessary to use one of the derivations of \placefloat in order to get the reference generated. In your case this would be \placefigure thus: \starttext \placefigure [ ] [clock] { } {\externalfigure[clock.jpg]} \at[clock] refers to a clock \stoptext

The fix is not really a fix thought, as it makes the image of the figure disappear. Still don't know how to make a .jpg work with \at

Hello, perhaps this is how it is supposed to work, but:

\externalfigure[clock.jpg][clock] \starttext \at[clock] refers to a clock \stoptext

produces "?? refers to a clock", instead of "1 refers a clock" --- the wiki of \at says, that labels of figures can be refered to. Is this a bug, or can only some labels be refered to? I was able to fix it using:

\reference[clock]{\externalfigure[clock.jpg]} \starttext \at[clock] refers to a clock \stoptext

and

\externalfigure[clock][] \starttext \at \stoptext

produces an interesting artwork... so I thought maybe this could be a bug. LMTX 2021.10.21

Hi,

Your example has two issues, since you invoke \externalfigure before \starttext, and moreover you don’t use the place figure mechanism. The following gives the result you want:

\setupinteraction[state=start] \starttext \startplacefigure[reference=clock] \externalfigure[clock.jpg] \stopplacefigure In figure \at[clock] you see a clock \page In figure \at[clock] you see a clock.

Or better: in \in{Figure}[clock] you see a clock. \stoptext

With \in you the value of the float counter while \at shows the page where the float is placed. The original example passed a name to the optional argument of \externalfigure but when you do this you just access a named list of figure options, e.g. rotating the image by 90 degrees counter clockwise. \setupexternalfigures[location={local,global,default}] \defineexternalfigure[rotated][orientation=90] \starttext \externalfigure[hacker.jpg][rotated] \stoptext Wolfgang
