Google doesn't index images?

Question

Google

For more than a month, the site pcwallpapershd.com , but Google does not want to index the pictures. he walks on them (I see this in the server logs) and the pages are in the search, but in the search for pictures 60 at the moment. Maybe someone had this? Domain clean for manual measures added to searchconsole. I looked in the webarchive - everything is clean, there was a thematic site on the domain.
