There are up to 30 UK websites hosting so-called revenge porn, which should be seen as a "criminal sexual offence against its victims," said the former Culture Secretary Maria Miller.
At PMQs, the Tory MP raised the issue of the posting compromising pictures of former partners online.
David Cameron said it was a "dreadful thing", and praised the work of his former cabinet member.
