(Yicai Global) April 16 -- Troubled commercial image provider Visual China [SHE:000681] has opened at the 10 percent limit down for the third trading day in a row, starting at CNY20.41 (USD3.04) today. The firm's website has been out of service since April 12 after public uproar over its attempts to claim copyright to the world's first-ever image of a black hole. 

Chinese regulators are investigating the firm, which also sells images of the national flag and emblem.
