Convert Image to Bytes. public static byte [] ImageToByte2(Image img) { byte [] byteArray = new byte [0]; using (MemoryStream stream = new MemoryStream()) { img.Save(stream, System.Drawing.Imaging.ImageFormat.Png); stream.Close(); byteArray = stream.ToArray(); } return byteArray; } In the code behind use Convert BMP file to img. System.Drawing.Image img = null ; img = System.Drawing.Image.FromFile(Server.MapPath(_ImageUrl)); var imgArr= ImageToByte2(img); string base64String = Convert.ToBase64String(imgArr= , 0, imgArr= .Length); Image1.ImageUrl = "data:image/jpeg;base64," + Convert.ToBase64String(base64String)

add this code protected void Page_Load( object sender, EventArgs e) { Bitmap bitmapimg = new Bitmap(120, 120, PixelFormat.Format32bppArgb); Graphics grph = Graphics.FromImage(bitmapimg); SolidBrush br = new SolidBrush(Color.Green); grph.FillEllipse(br, 4, 4, 110, 110); Response.ContentType = "image/gif" ; bitmapimg.Save(Response.OutputStream, ImageFormat.Gif); bitmapimg.Dispose(); }

Hema, If it is Ok with you to use a programming toolkit other than the default .NET classes, you can check the HTML5/JavaScript ImageViewer control from LEADTOOLS. They have an online demo here: http://demo.leadtools.com/JavaScript/Viewer/ And the following JavaScript code shows how you can load a hosted BMP image using the imageViewer control from LEADTOOLS: "en" > ImageViewer Example "text/javascript" > window.onload = function () { // Get the parent div for the image viewer var div = document.getElementById( "imageViewerContainer" ); // Create a new image viewer instance var createOptions = new lt.Controls.ImageViewerCreateOptions(div); var imageViewer = new lt.Controls.ImageViewer(createOptions); // Load an image into it imageViewer.imageUrl = "http://localhost/images/image1.bmp" ; } "imageViewerContainer" style= "width:800px; height:800px" >

Hi hemalatha, I just tested with Image Control and a sample bitmap image in sample asp.net web application. It is displaying the image of extension .bmp. I think this is not the problem with Image Control. It is supporting .bmp files. I am attaching sample for your reference. Thank you.
