A photo of Homer Simpson accompanying a genuine article about multiple sclerosis (MS) has exposed Chinese state-run media's penchant for using images without permission.

The article, which appeared on China's official Xinhua News Agency's English news site on Monday, displays text about a new genetic discovery relating to MS, attributed to "agencies." Alongside is an x-ray rendering of the diminutive brain of the cartoon character Homer Simpson, attributed as a "file photo."

This isn't the first time Chinese media has fallen prey to satire presented to an English-language audience. In 2002, the Beijing Evening News (Beijing Wan Bao) picked up an article from humour site The Onion, stating that the U.S. Congress had threatened to move out of the Capitol building in Washington, D.C., unless the building were upgraded to include a retractable dome. The newspaper also ran a drawing The Onion had published of the fictional new roof design.

Both online and print media in China routinely use photos downloaded or scanned from other sources without proper attribution or copyright permission.

Strangely, publications in foreign languages, and therefore those most likely to be read by foreigners, are frequent offenders. Last year, the state-run English-language newspaper China Daily's Web site ran 13 topless images of a female Italian volleyball player, clearly marked both with logos for the magazine Men's Health and an Italian Web site.
