Question

I have a folder C:\Images which has a some images. This folder is not inside my project and I would to know if there is a way to load an image from that folder on to an ASP.NET Image control.

<asp:Image ID="img" runat="server" />

One solution could be to make the Images folder a Virtual directory on the IIS but I would like to know if this can be done without creating a virtual directory for the Images folder.

Assuming proper access is granted to the Images folder you could do something like this:

Your main page:

protected void Page_Load(object sender, EventArgs e)
{
    mainImage.ImageUrl = "ImageHandler.ashx?image=MyImage.jpg";
}

ImageHandler:

public void ProcessRequest(HttpContext context)
{
    byte[] imageBytes = File.ReadAllBytes(@"C:\Images" + context.Request["image"]);
    context.Response.ContentType = "image/jpeg";
    context.Response.BinaryWrite(imageBytes);
}
