I found a workaround: Defining the image as a symbol and using that as “text”
does not annoy Vera.
\setupbackend[format=pdf/ua-2]
\setuptagging
[state=start,
preset=basic,
level=2,
option=interaction,
comment={Cows}]
\setupexternalfigures[location=default]
\setupinteraction[state=start]
\definesymbol[d-hexo][{\offset[bottomoffset=-.33em]{\externalfigure[cow]
[height=1.33em,
alternativetext={Link to Cow}
]}}]
\starttext
Go to the \goto{\symbol[d-hexo]{}}[url(http://wiki.contextgarden.net)].
\stoptext
