Make money from Blogs - Relating your Flickr photos to your Wordpress blog

There are many different ways you have to express yourself, such as doing so through social networking sites such as Facebook and MySpace, through photo sharing sites such as Picasaweb, Flickr, Photos on Facebook, personal blogs, and so on; similarly you can share on blogging sites such as Wordpress, Blogger, and so on. Unfortunately, many of these sites are not linked, and you would be finding yourself duplicating some of your work. Consider the example of a great photo that you want to put on Flickr, and also share on your blogs at Wordpress or Blogger. So, what do you do ? Well, the hardest way is to upload these to all the services individually, while manually tracking the status of which photo has been updated to which site. The smarter way is to figure out how to upload at one place, and use elsewhere in a smart way with minimum effort. Google already does that at Picasaweb since it owns both Blogger and Picasaweb; so a photo updated to Blogger actually is stored at an album in Picasaweb.
If you are a great user of Flickr and Wordpress, then there is a solution available to you as well. This is in the form of leveraging the Flickr API to make this connection, and here is a Wordpress Plugin that allows you to do that (link to plugin page - called Flickr Photo Album for WordPress). Read more on the site:

This Flickr plugin for WordPress will allow you to pull in your Flickr photosets and display them as albums on your WordPress site. There is a pretty simple template provided, but you can customize the templates 100% to match the look and feel of your own site. And if you want, you could also hook it up with Lightbox or any other number of display libraries.
On the backend, this plugin will also add a new Flickr icon to your WordPress edit screen which will allow you to easily insert your Flickr photos into your blog posts with just a couple clicks. You can either have your inserted photos link back to your WordPress Flickr photo album or directly to your Flickr.com photo page.

Installation instructions along with a detailed feature set are available on the page.

WWW - The Server Side

For all the incoming connectionts from different clients, every website is associated with a server process listening to TCP port 80. The client sends a request after the connection is made and the server sends the reply and then the connection is released. The protocol that is responsible for requests and replies is called HTTP.

The steps that occur between the user clicking and a page being displayed are:
- The browser determines the URL.
- The browser asks DNS for IP address.
- DNS replies.
- Browser makes a TCP connection to the port.
- It then sendsthe GET command.
- The server sends the file.
- The TCP connection is released.
- The browser displays the text of the file.
- The browser fetchesand displays all images of the file.

Not all servers speak HTTP, Old servers use FTP, Gopher or other protocols. Given the number of different protocols, it was thought impractical to make browser understand different protocols. However, since there is a need to make information available (where the server talks in protocols other than HTTP), a solution was required. This solution is something called a proxy server. A proxy server takes a HTTP request from the browser and translates these requests into the FTP/Gopher/other protocols. The proxy server is a separate logical server.
A proxy server also serves to provide an important function called caching. Through caching, a proxy server keeps a local copy of the pages that pass through it. If a user requests for a page, if the page is present on the cache of the proxy server, it serves the page to the user. this way it serves to reduce load on final server.
