Viewing Flicker Images on Windows 7.1 Phone or Mango Phone

In this article I will show you how you can create a Photo Viewer from images of the Flicker Service.

Flicker Service

Flicker exposes a REST based feed to access images. You can find information about Flicker public feeds at the following link.

Public images feed can be found at:

Expected Output



  1. Call Flicker Service
  2. Parse XML feed
  3. Bind it to List Box.

Create Windows Phone 7.1 Application

Create a Windows 7 Phone Application and select Windows Phone 7.1 as the target Windows Phone version.



Create Photo class

To bind images to the ListBox, let us create a Photo class. Right-click and add a class called Photo to the project. When we parse Flicker Image feeds, we will bind a public Image URL here.



Parsing Image Feed of Flicker Service

When you open a public feed URL of Flicker in browser, you can view the feeds in the browser itself.


We are going to give value of link element from the feed in Image as source value.

We will have to make asynchronous calls as below:


Then in DonwnloadStringCompleted event, we will have to perform the following tasks:
  1. Create an observable collection of photos
  2. Parse the feed
  3. Iterate through all the public image url in feed and add to collection.


Parsing of feeds can be done as below:
  1. We are parsing Link URL.
  2. Fetching the value of href attribute in Link URL.
  3. There are two link elements and we are fetching the value of a link element having rel attribute value as enclosure


Design the Page

We are going to put a ListBox in content grid and inside ItemTemplate of ListBox , we will put Image control.


As the source of the Image you need to bind PhotoSource property of Photo class.

For Reference the full source codes are given below. Feel free to use for your purpose.

Run the Application

Press F5 to run Photo viewer.


I hope this post was useful. Thanks for reading. In future articles, I will show you how to fetch Images from a server instead of attaching them as resources.
