MacJunkie has re-launched its Mac-related virtual postcard collection, jCards, this time with a new twist.

This is a new generation of Mac greeting cards based on photos sent in by MacJunkie’s online readership. The original incarnation of the cards was terminated following pressure from Apple’s legal department, as was Mac Cards, who launched an alternative, copyright-free service last week.

The idea is to create a set of cards over which Apple has no copyright control for the free use of Mac people seeking an alternative to the cards offered on Apple’s own iCards Web service.
