"for file in *" doesn't correctly parse files containing spaces in their filenames. For example file "an image of duck.jpg" will be interpreted as 4 files "an" "image" "of" "duck.jpg"

  Yes, it does.

  Your problem is (probably, since you didn't include an example) that
  you omitted quotes around its expansion, e.g.:

printf '%s\n' $file

  That should be:

printf '%s\n' "$file"
