Question

Answer 1

The documentation states that the accept rule only accepts mime-types as an argument.

If you wanted to accept all images then use image/*.

If you want to accept only specific image types then you can specify multiple mime-types by separating them with a comma, e.g. image/pjpeg,image/jpeg,image/png,image/gif.
