Its WinForms alright... Why dont you try out some controls and see what works :) If you get stuck tell us were you are stuck. Your question seems to imply that you need permission from us before you try it out. You dont :)

<asp:Image ID="Image1" ImageUrl="~/Handler.ashx" runat="server" />
in the handler i write code as
Paloma.TargaImage tgaImage = new Paloma.TargaImage("C:/my folder/TargaReaderDemo/Image/img.tga");
context.Response.ContentType = "image/tga";
context.Response.BinaryWrite(byteArray);
context.Response.End();
but not working ????

Try this,

Download the source from .NET Targa Image Reader[^]
Include the TargaImage.dll in bin folder and reference it to the project,

In aspx code,

C#

<asp:Image ID="Image1" ImageUrl="~/Handler.ashx" runat="server" />

In Handler.ashx,
using System.Drawing;

C#

Bitmap tga = Paloma.TargaImage.LoadTargaImage(@"C:/my folder/TargaReaderDemo/Image/img.tga");
            Response.ContentType = "image/jpeg";
            tga.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);
