Corbis is offering Internet bloggers access to some of its images for their posts for free in exchange for showcasing advertising embedded into the photos.

Corbis will allow bloggers to access photos via a Web link from the site PicApp.com, now in a test phase.
The photos will either include an ad overlay on part of the image, or embedded advertising that pops up when a Web user runs a cursor over the picture.

PicApp also offers bloggers the opportunity to earn ad revenue based on how many times Web users click on the images posted to their blogs.
