use UrlEditor, seehttp://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwebuidesignurleditorclasstopic.asp[EditorAttribute(typeof(System.Web.UI.Design.UrlEditor), typeof(UITypeEditor))]
public string URL
{
    get
    {
        return http_url;
    }
    set
    {
        http_url = value;
    }
}
if you want to use ImageUrlEditor[Category("Buttons"), 
 DefaultValue(""), 
 Description("First button's image URL."), 
 <B>EditorAttribute(typeof(System.Web.UI.Design.ImageUrlEditor), 
 typeof(System.Drawing.Design.UITypeEditor))</B>] 
public string FirstButtonImageUrl 
{
   get { object o = ViewState["FirstButtonImageUrl"]; 
         return (o==null) ? String.Empty : (string) o; }
   set { ViewState["FirstButtonImageUrl"] = value.Trim(); } 
}
