  1. show image in gridview / any image control from db.. 

  you can make new page or use ashx handler to get image for you from db and set this page path in imageurl and pass the imagename name as parameter 

  see the following example 

  Display Images In GridView From DataBase C# VB.NET

  and for resizing see the example 

  Resizing images retrieved from SQL server

  in .aspx.cs page , dynamically set the IMageUrl for image
  img.ImageUrl= "MyHandler.ashx?myImageID=blueimage";
  
  
  
  in .ashx page
    public void ProcessRequest(HttpContext context)
          {
              string imagename = context.Request.QueryString.Get("myImageID").ToString();
              // using the image name, use SQLDATAADAPTER and get the image
              // by filling DATASET and type cast to byte[] (byte array)
              byte[] imageBinaryData = new byte[100];// this is just for testing purpose .. u need to get data from sql.. showing u the syntax
  
              context.Response.BinaryWrite(imageBinaryData);
          }

  Thanks
