What i get is
src = Request.QueryString["imgsrc"];//src = "images/file 15.jpeg";
System.Drawing.Image image = System.Drawing.Image.FromFile(Server.MapPath(src));
the second line returns System.IO.FileNotFoundException cause of the space in the path.
What should i do to encode or do something to read this kind of paths;
Assign Server.MapPath(src) to a temporary variable and then make sure that the path points to an existing file:
src = Request.QueryString["imgsrc"];//src = "images/file 15.jpeg";
string tempPath = Server.MapPath(src);
Debug.Assert(System.IO.File.Exists(tempPath);
System.Drawing.Image image = System.Drawing.Image.FromFile(tempPath);
