Question

If I can retrieve image data from sql-server database, which stored as image type. How can I display the image in my web application using c#? Thanks in advance.

You have to create an http handler that returns the image

public void ProcessRequest(HttpContext context)
        {
            Byte[] yourImage = //get your image byte array
            context.Response.BinaryWrite(yourImage);
            context.Request.ContentType = "image/jpeg";
            context.Response.AddHeader("Content-Type", "image/jpeg");
            context.Response.AddHeader("Content-Length", (yourImage).LongLength.ToString());
            con.Close();

            context.Response.End();
            context.Response.Close();
        }

You can can do that by creating a GenericHandler file type from the visual studio and add the previous code in then you can call you can write the url of the generic handler as the image source
