提取图像，未经授权的访问异常错误

Question

I am fetching json data in which there is a link to again fetch an image

For example:

{"status":"403","message":"Not Authorized","image":"http:\/\/abc.com\/images\/1.jpg"}

status, message n image are retrieved perfectly fine as i displayed there value in a text box.

Further I wanted to display image so I do:

public string link = ClassName.variableName;

link now holds the value http//abc.com/images/1.jpg . I displayed its value in text box and its fine. So I moved further:

BitMapImage MyImage = new BitMapImage( new Uri (link, UriKind.RelativeOrAbsolute));

image1.source = MyImage;

But when I run it shows error "UnAuthorized access exception unhandled ". To cross check I opened a new project and instead of fetching the data, I directly provided a link into the image source and the image was displayed.

BitMapImage MyImage = new BitMapImage( new Uri ("http//abc.com/images/1.jpg", UriKind.RelativeOrAbsolute));

image1.source = MyImage;

Here it works fine. Image is displayed.
