Wolfgang,
Thanks for the suggestion. However, I'm using ConTeXt to typeset arbitrary XML
input from users (and therefore arbitrary image filenames). While your idea
works for the two examples that I gave, it doesn't work if the curly braces
aren't balanced in the filename (e.g., "flower{1.jpg"). Is there any general
character escaping mechanism for macro arguments?
Cheers,
Mike

Yould could define symbolic names for the figures and access the
figures with this name, this allows you also to use bracketrs in the
file names.
\useexternalfigure[brace flower][flower{1}]
\useexternalfigure[bracket flower][{flower[1]}]
\starttext
\externalfigure[brace flower]
\externalfigure[bracket flower]
\stoptext
