I am creating an ASP.Net Web application. I have a image control that displays a graph. I want to display this graph dynamically. Based on the user selection for the options, the graph gets changed, I get a new graph image as a file. I need to save the image on client side. And then set the property of img as ImgUrl = "filename".Which directory I need to access to save image? How will I get the path at client side?I tried using System.IO.Path.GetTempPath() function, but it gave me some ASPNet user path, I don't think it worked properly.Any help will be appreciated.Thanks.
