The owner of a digital billboard company is blaming a hacker for posting a large, lewd photo on the company's roadside signs in Alabama.

Rush-hour commuters in the city of Enterprise got an eyeful of the sexually suggestive image Friday morning. The Enterprise Ledger reports (http://bit.ly/24QzRUL) that Bill Durden, who owns Durden Outdoor Display, said the same photo showed up on his billboards in Dothan and Fort Rucker.

Durden said the prank appeared to be the work of someone who hacked his company's computer system. He said he planned to ask police for help tracking down the culprit.

Durden said his company had tightened its security system and he "does not foresee this happening again."
