Refetch broken images in batch download

Sometimes one or more images can't be fetched (server issues, network issues, other errors) and in such cases the red rectangle will appear in the middle of properly fetched images (in the place where the missing image should be). This red rectangle has tooltip under contained full link to image but there is no option to refresh such image. It would allow addon to try to check this failed image once again without the need to check whole page again, but for now it is not possible to do this. Maybe it is this way due to filter which excluded image because addon couldn't get proper size, i don't know. The only way is to repeat operation of detecting everything on such site.

Where should we place the reload button?

Note that you can refresh the picker (F5) to reload broken images. Since loaded images are cached, the extension only re-fetch broken images.
