Flickr, Picasa: What is it?
Two popular social photo sharing Web sites, Flickr and Picasa, allow users to post pictures that are generally visible and available to everyone else. Anybody can view and download these photos. It is important to abide by the community guidelines and be cautious of what you upload. Guidelines are available at:
 
Flickr (guidelines)
Flickr is an image and video hosting Web site, Web services, suite, and online community platform. A popular Web site for users to share personal photographs, the service recives wide use by bloggers as a photo repository.
 
Picasa (guidelines)
Picasa is a software application for organizing and editing digital photos. “Picasa” is a blend of the name of Spanish painter Pablo Picasso, and the phrase mi casa for “my house,” and “pic” for pictures (personalized art).
 

What can I do with it?
Photo-sharing sites

Flickroffers two types of accounts: Free and Pro. Free account users may upload 100 MB of images a month and two videos. For the free user, only the most recent 200 photos will be visible in the “photostream.” The other photos are still stored on the site and links to these images in blog posts remain active. Free users can also contribute to a maximum of 10 photo pools. Flickr deletes any free account that stays inactive for 90 consecutive days.
 
Flickr’s Pro accounts allow users to upload an unlimited number of images and videos every month. A Pro user receives unlimited bandwidth and storage, and may place photos in up to 60 group pools. Pro users also receive ad-free browsing and access to account statistics.
 
Flickr asks photo submitters to organize images using tags (a form of metadata), enabling searchers to find images related to particular topics, such as place names or subject matter. Flickr was an early implementer of tag clouds, which provide access to images tagged with the most popular keywords. Flickr lets the user organize photos into “sets,” or groups of photos that fall under the same heading. Sets are more flexible than the traditional folder-based method of organizing files, as one photo may belong to one set, many sets, or none at all. The user may group sets into “collections.”
 
Flickr also offers a fairly comprehensive Web-service API that lets programmers create applications.
 
Flickr provides both private and public image storage. Users can set privacy controls that determine who can view the image. A “guest pass” allows private photos to be shared with non-Flickr members. Many members let anyone view their photos, and form a large collaborative database of categorized photos. Other members can leave comments about any image they have permission to view, and in many cases, can add to the list of tags associated with an image.
 
Picasaprovides file-importing and tracking features for organizing photos, as well as tags, facial recognition, and collections for further sorting. The service also offers several basic photo-editing functions, including color enhancement, red-eye reduction and cropping. Other features include slide shows, printing and image timelines. Images can be prepared for external use, such as for e-mailing or printing, by reducing file size and setting up page layouts. Users may also take advantage of integration with online photo printing services.
 
Picasa offers a search bar that is always visible when viewing the library. Searches are “live,” in that displayed items are filtered as you type. The search bar will search filenames, captions, tags, folder names, and other metadata. You can even search for images that contain certain colors. Picasa uses technology to search for features within photos, such as people or buildings.
 
Picasa has no separate view window. The service provides only an “edit view” with a viewing area. Full-screen view is available in slideshow mode.
 
Picasa Web Albums (PWA) is a photo-sharing Web site from Google, often compared to Flickr and similar sites. It allows users with accounts at Google to store and share 1 GB of photos free of charge. In both paid and free accounts, the actual resolution of the photo is maintained (even though a smaller resolution photo may be displayed by the Web interface), and the original photo can be downloaded.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Tips
  • Keep your Flickr account active. Flickr will delete it after 90 consecutive days of inactivity.
  • To view a full-screen image in Picasa, hold down the ctrl+alt keys while in “edit view,” or press the Alt Gr key.
  • Mac users take note. On January 5, 2009, Google released a beta version of Picasa for Mac (Intel-based Macs only). Also, a plugin is available for iPhoto to upload to the Picasa Web Albums hosting service. There is also a stand-alone Picasa Web Albums uploading tool for OS X 10.4 or later.
