Can I make images available offline?

When I copy a text with images from the web, and I paste them in LibreOffice Writer, everything works fine. However, the images aren’t saved with the file, but linked to the file on the web.

When I want to consult the file on a device without internet connection, or the image doesn’t exists anymore on the webpage, there will be no more images in the document.

Is it possible to make the images offline available (saved with the document)?

Yes : menu Edit > Link … then select alls links in the dialog and hit the button “Break link” validate and save the file.
