Web Services & nb p; 2.0: Flickr

Every day, Web 2.0 services are becoming more and more. There are even those who have achieved amazing results, and their value is expressed in millions of dollars. The leader among the encyclopedias is Wikipedia. If bookmarked, then delicious. The blog posting service is Blogger.
If a social network, then MySpace. If the service for working with photos, then, of course, Flickr.
We haven’t written much about Web 2.0 services. Therefore, we will try to fill this gap. Let’s start, perhaps, with the most famous service for working with digital photos – Flickr.

Flickr is not just photo hosting. This service is widely used by bloggers to store photos. But Flickr is not just photo hosting. This is a convenient categorization of your photos, which will facilitate your search. These are descriptions of the elements directly on the photo itself. This is a grouping. This is a mass of other features. But first things first.

How it all began
Flickr was developed by Ludicorp.Flickr was developed by Ludicorp in February 2004. The company was going to develop a multiplayer online game, but the result was the Flickr photo service. That’s how it is!

In March 2005, the company and, accordingly, Flickr acquired Yahoo !. And on March 16, 2006, Flickr moved from the Beta discharge to the Gamma discharge: this means that a thorough inspection of Flickr was conducted and no failures were identified. Finding a project in Gamma (alpha, beta, gamma means that the project is in the testing phase) they explain as follows: “This is our way of showing you that the site is in a state of continuous improvement.”
Flickr has quite a number of options. All of them are created in order to facilitate the search for the photos you need. Let’s look at them …

In order to start working with Flickr, you need to register first. There are two registration options: for those with a Yahoo! and for those who do not have it. Choose the one that suits you and register. The registration process does not take much time.

The service is free, but if you want more, then, as they say, pay. A free account allows you to upload up to 20 megabytes of photos per month. Paid allows you to download up to 2 gigabytes per month and has some advantages.

The categorization of photographs takes place on the principle of folksonomy, that is, tagging. The categorization of photographs occurs on the principle of folksonomy, that is, tagging. For each photo you specify a specific set of tags (keywords). This will make it easier in the future to find the right photos (both for you and for other users who are looking for specific photos).

A very interesting feature of Flickr is geotagging. It allows you to “post” photos on the world map. That is, depending on where the photos were taken, you choose their place on the map. Yahoo! map Maps is integrated into Flickr. To work using Ajax (as without it in the services of Web 2.0?). By the way, it is worth noting that Ajax works very stably and is used only where it is needed. For example, you want to see photos of a place where you have not been for a long time. Just enter the name of the city in the line “Location search” and right there in front of you a map appears with the labels that indicate the location of the shooting. Very comfortably!

In addition to tagging and geotagging, Flickr allows you to combine photos into so-called sets, or simply albums. They differ from regular file folders in that the same photo can be added simultaneously to several albums.

For each photo you can set certain access rights. For example, if you do not want your photograph to be seen by other visitors and users of the service, specify “Only you” in the access rights. If it should be available to you, your “friends” and / or family, tick this off. If you want your photo to be available to everyone, check “Any one”. In general, everything is approximately as it is implemented in LiveJournal.

In fact, Flickr is reminiscent of LiveJournal, only for posting photos, not posts. The same “friends” (although in Flickr, in addition to “friends” there is also “family”), the same communities (only in Flickr they are called pools), the same access rights, the same “memoriz” ( in Flickr – Favorites).

A very useful feature of Flickr is the ability to add notes directly to a photo. For example, your photo shows a lot of things. With the help of Flickr you can arrange the names, or a brief description of these things directly on the photo. Or, for example, the photograph shows a group of people. Thanks to this feature, you can sign the names of each.

In addition to the usual “uploader” there are programs that allow you to upload photos to your account – Flickr Uploader. Of course, the program supports drag-and-drop (just drag the photo with the mouse and that’s it!).
