From Psychedelic-Traveller

We would like to invite you to present your pictures here also! Something that's very easy to do using flickr.com. flickr.com is a platform onto which, once you're registered, you can upload up to 100MB of pictures a month that you can then organise into groups or 'pools' for free. With applications this pictures will be shown on our's and some and some connected sites and (my)spaces.

You can invite your friends to join these pools and they can then contribute their pictures too. This way, large picture communities develop and you're certain to find something of interest amongst them.

You'll find the Psychedelic Traveller pool under http://www.flickr.com/groups/psychedelic-traveller/pool there are already some selected pictures from all around the world.

Flickr

From Wikipedia, the free encyclopedia

Flickr is an image and video hosting website, web services suite, and online community platform. In addition to being a popular website for users to share personal photographs, the service is widely used by bloggers as a photo repository. As of June 2009, it claims to host more than 3.6 billion images, up from 3 billion in November 2008. Once you're registered, you can upload up to 100MB of pictures a month that you can then organise into groups or 'pools' for free. You can invite your friends to join these pools and they can then contribute their pictures too. This way, large picture communities develop and you're certain to find something of interest amongst them.

Features

Organization

Flickr asks photo submitters to organize images using tags (a form of metadata), which allow searchers to find images related to particular topics, such as place names or subject matter. Flickr was also an early website to implement tag clouds, which provide access to images tagged with the most popular keywords. Because of its support for tags, Flickr has been cited as a prime example of effective use of folksonomy, although Thomas Vander Wal suggested Flickr is not the best example.

Flickr also allows users to organize their photos into "sets", or groups of photos that fall under the same heading. However, sets are more flexible than the traditional folder-based method of organizing files, as one photo can belong to one set, many sets, or none at all. Flickr's "sets", then, represent a form of categorical metadata rather than a physical hierarchy. Sets may be grouped into "collections", and collections further grouped into higher-order collections.

Finally, Flickr offers a fairly comprehensive web-service API that allows programmers to create applications that can perform almost any function a user on the Flickr site can do. To use the Flickr API, users need to know their Flickr NSIDs. Several sites have been developed to aid users in this, including idGettr and What Is My Flickr Id.

Organizr

Organizr is a web application for organizing photos within a Flickr account that can be accessed through the Flickr interface. It allows users to modify tags, descriptions, and set groupings, and to place photos on a world map (a feature provided in conjunction with Yahoo! Maps). It uses Ajax to emulate the look, feel, and quick functionality of desktop-based photo-management applications, such as Google's Picasa and F-Spot. Users can select and apply changes to multiple photos at a time, making it a better tool for batch editing than the standard Flickr interface.

Access control

Flickr provides both private and public image storage. A user uploading an image can set privacy controls that determine who can view the image. A photo can be flagged as either public or private. Private images are visible by default only to the uploader, but they can also be marked as viewable by friends and/or family. Privacy settings also can be decided by adding photographs from a user's photostream to a "group pool". If a group is private all the members of that group can see the photo. If a group is public the photo becomes public as well. Flickr also provides a "contact list" which can be used to control image access for a specific set of users in a way similar to that of LiveJournal.

In November 2006 Flickr created a "guest pass" system that allows private photos to be shared with non Flickr members. For instance, a person could email this pass to parents who may not have an account to allow them to see the photos otherwise restricted from public view. This setting allows sets to be shared, or all photos under a certain privacy category (friends or family) to be shared.

In March 2007, Flickr added new content filtering controls that let members specify by default what types of images they generally upload (photo, art/illustration, or screenshot) and how "safe" (i.e., unlikely to offend others) their images are, as well as specify that information for specific images individually. In addition, users can specify the same criteria when searching for images. There are some restrictions on searches for certain types of users: non-members must always use SafeSearch, which omits images noted as potentially offensive, while members whose Yahoo! accounts indicate that they are underage may use SafeSearch or moderate SafeSearch, but cannot turn SafeSearch off completely.

Many members allow their photos to be viewed by anyone, forming a large collaborative database of categorized photos. By default, 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.

Interaction and compatibility

Flickr's functionality includes RSS and Atom feeds and an API that allows independent programmers to expand its services.

The core functionality of the site relies on standard HTML and HTTP features, allowing for wide compatibility among platforms and browsers. Organizr uses Ajax, with which most modern browsers are compliant, and most of Flickr's other text-editing and tagging interfaces also possess Ajax functionality.

Images can be posted to the user's collection via email attachments, enabling direct uploads from many cameraphones and applications with email capabilities.

Flickr has increasingly been adopted by many web users as their primary photo storage site, especially members of the weblog community. In addition, it is popular with Macintosh and Linux users, who are locked out of photo-sharing sites that require Windows and Internet Explorer.

Flickr uses the Geo microformat on the pages for over 3 million geotagged images.

Flickr has entered into partnerships with third parties to offer printing of various forms of merchandise, including business cards, photo books, stationery, personalized credit cards, and large-size prints, from companies such as Moo, Blurb, Tiny Prints, Capital One, Imagekind, and QOOP. In addition, Flickr has partnered with Getty Images to sell stock photos from some users.

Users of Windows Live Photo Gallery and Apple's iPhoto (version 8) have the ability to upload their photos directly to Flickr.

Flickr provides a desktop client for Mac OS X and Windows that allows users to upload photos without using the web interface. Uploadr allows drag-and-drop batch uploading of photos, the setting of tags and descriptions for each batch, and the editing of privacy settings.

Filtering

In March 2007, Flickr introduced mandatory filtering of all photos and a process of central review of photos by staff to set levels of appropriateness. By default all Flickr accounts are set to the status appropriate for a minor and must be changed by the user in their account.

Flickr has since used this setting to change the level of accessibility to "unsafe" content for entire nations, including South Korea, Hong Kong, and Germany. In summer 2007, German users staged a "revolt" over being assigned to the user rights of a minor. See Censorship controversy below.

The filter system of Flickr assumes that photos may be unsafe and should not be public until a staff person has validated that the material is safe. Until this happens, which could take up to a month, material cannot be viewed by persons without a valid Yahoo and Flickr account. A Flickr site not marked as safe can only be viewed by people in the community who have set their filters beyond the default status of that of a "minor".

Licensing

Flickr offers users the ability to either release their images under certain common usage licenses or label them as "all rights reserved". The licensing options primarily include the Creative Commons 2.0 attribution-based and minor content-control licenses - although jurisdiction and version-specific licenses cannot be selected. As with "tags", the site allows easy searching of only those images that fall under a specific license.

Map sources

In addition to using commercial mapping data, Flickr now uses OpenStreetMap mapping for various cities; this began with Beijing during the run-up to the 2008 Olympic games. As of October 2008, this is used for Baghdad, Beijing, Kabul, Sydney, and Tokyo. OpenStreetMap data is collected by volunteers and is available on a CC-BY-SA 2.0 license from Creative Commons.
