The poster child of this Sawyeresque business model is the photo-sharing site called Flickr.

Facebook is the largest photo-sharing site in the world, with its 800 million members uploading an average of more than 250 million photos per day.

The application has built-in sharing so that photos or videos can be uploaded to photo-sharing sites or used on a computer.

Flickr is a photo-sharing site that allows users to upload their shots and videos for free.

Flickr - the world's leading photo-sharing site, where people create profiles, upload photos and chat to each other - didn't emerge into the world fully formed.

Webshots, like several other photo-sharing sites, lets consumers upload their digital photos to a Web page on the site, free of charge.

They can be helpful tools that let you do calculations in a browser window or upload pictures to a photo-sharing site.

This has been its model with other acquisitions like Flickr, a photo-sharing site, and Del.icio.

Early last year, Yahoo bought Flickr, a photo-sharing site, for an undisclosed sum.

In general, photo-sharing sites allow you to create a password that you can send to friends or family so only they can see your online photos.
