{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {


            // call web service here
            SmartPosterV1 a = new SmartPosterV1();

            MemoryStream mem = new MemoryStream(a.returnTestImage());

        }
    }
}

PictureBox is a WinForms control, and it’s Image property is a System.Drawing.Image.

In ASP.Net, you need to have a System.Web.UI.WebControls.Image in your web form and assign the ImageUrl property the URL of the image to be displayed.
