Can wget convert links within a local html document?

I know that wget can fetch a remote page and its dependencies and rewrite the html so that image src attributes reference the newly downloaded images.

I am trying to convert local html files that reference images on the Internet. I'm using

wget --mirror --page-requisites --convert-links \
     --directory-prefix=foo \
     --force-html \
     --input-file=my_file.html

All of the referenced images are downloaded to the appropriate places in foo/ but the src attributes in my_file.html aren't being changed.

Try this:

wget --recursive --page-requisites --convert-links --span-hosts http://localhost/some.html
