If I understand your suggestion correctly, specifying name doesn't work.

\externalfigure[][name=flower[1].jpg]
\externalfigure[name=flower[1].jpg]

Cheers,

I'm encountering the situation where users are choosing images that may contain brackets or curly braces (e.g., flower[1].jpg or flower{1}.jpg).
