Optionally fetch the images from the additional urls

[Konecho]

When importing a url from danbooru, I sometimes get a page that says This page has been removed because of a takedown request. The parser can still get the tags and source urls, but the download status is marked as ignored because the image cannot be found. I would like to get the image from the source urls and use the tags from danbooru (this is because the original post source may be twitter or other webside which has no tags).

Besides, my url downloader page has many file download logs that are marked as ignored, how do I batch export their source urls in additional urls instead of sources?
