Google has added PicApp to its Knol (Unit of knowledge) project. Knol is intended to build a user generated library of written content similar to Wikipedia. The usage of PicApp will allow users to allow licensed images in articles. The images can be used free of charge.
“The new picker enables you to search for creative and editorial images from PicApp’s comprehensive, high-quality stock imagery repositories such as Getty Images. The service and use of the images is free.”
The feature was launched last month and has been used by a number of authors. PicApp integrates with a number of other applications allowing users to add imagery. Revenues are generated via advertising that appears with the used images.
