You can use server.MapPath, pass Url string as given below.

 Server.MapPath("../images/image.gif")

Use Server.MapPath. And it's a good practice to use the tilde char ~ to specify the web application root.

Bitmap b = new Bitmap(Server.MapPath("~/uploadedimages/sampleimage.jpg"));

if uploadedimages directory is in your App_Data folder then you should append the App_Data absolute path to your path:

Bitmap b = new Bitmap(Path.Combine(Server.MapPath("~/App_Data"), "/uploadedimages/sampleimage.jpg"));
