The 'Crying Lightning' rockers recorded the LP in Joshua Tree, California, where the photograph that appears on the record's cover was also taken.
"We were heavily involved in the album artwork this time," drummer Matt Helders told The Sun. "It's a bold thing to be on the front of our album, even though we are still slightly disguised.
"It's a photo I took with a dollar camera. I bought a camera for a dollar while we were in Joshua Tree in the Californian desert. There were film students selling all this stuff off at ridiculously low prices."
Frontman Alex Turner added: "We're on the cover because it feels like the album is more ours somehow."
Humbug is due for release on Monday.
