Rich Text Editor Image Upload Handler

Rich Text Editor Image Upload Sample

I want to use imageupload handler for rich text editor but I couldn't complete the code.

<%@ WebHandler Language="C#" Class="imageupload"%>
using System;
using System.Web;
public class Upload : IHttpHandler{    
    public voidProcessRequest (HttpContext context) {
       HttpPostedFile uploads = context.Request.Files["imageupload"];
       string file = System.IO.Path.GetFileName(uploads.FileName);
       uploads.SaveAs(context.Server.MapPath(".") + "\\Images\\"+ file);
       string url = "/Images/"+ file;
       ..............
    }

    public bool IsReusable {
        get { return false; }
    }
}

Images from Rich Text Editor should be stored on the server as files. I couldn't adapt the code sample I found.
