This works here.
local ii="myImage", bb="Browser"
if there is no img ii then create img ii
put globalLoc(the topLeft of widget bb) into TL
put globalLoc(the botRight of widget bb) into BR
export snapshot from rect (TL,BR) to img ii as PNG
hide widget bb -- avoid artefacts from browser update
print card from (the topLeft of img ii) to (the botRight of img ii)
show widget bb
