Im Sokha was born in Kompong Cham. A compulsive drawer, he did not stay in school for long. In the 1980s flyers from Indian films captured his imagination, and he began drawing comics in many different genres - film adaptations, adventure stories, romance and horror. During the 1980s he was known as one of the fastest comic artists, able to draw an entire book in a few days. He previously worked as an editorial cartoonist for newspaper Kampuchea Thmey.
