I want to get the pixel size of a image file, which is specified by its URL. The problem is how to load the image file by a URL, and then how to get its size? I'm looking for any useful advices.
 
..NET makes this pretty easy using classes from the System.Drawing and
System.NET namespaces:

string imageUrl =
"http://msdn.microsoft.com/nodehomes/graphics/80x60/aspnet.jpg";

WebRequest request = WebRequest.Create(imageUrl);
WebResponse response = request.GetResponse();
Image image = Image.FromStream(response.GetResponseStream());

Console.WriteLine("Image size: {0}x{1}",
image.Width, image.Height);

HTH,
