Jeff Burke has retired as senior vice president for product strategy at Jupitermedia, owner of the Jupiterimages stock agency. Lorraine Triolo, Jupitermedia creative director and Burke's wife, also is leaving the company.

In the 1980s, the duo founded the PictureArt stock agency, which was acquired by Jupitermedia last year.

Burke will remain chairman of the Picture Licensing Universal System Coalition, which is seeking to develop a standard system of copyright and permission management for photographs.
