توی این کد به دنبال YOUR IMAGE بگردید و بجاش آدرس لوگو خودتون رو بزارید سپس با یه نام دلخواه و با پسوند CSS دخیره کنید و یه جا در سایتتون آپلود کنید
سپس در قایل index.template.php دنبال sampadia.com/forum/Themes/MicrosofT/style.css?fin11 بگردید و به جاش آدرس همین فایل CSS جدید رو بزارید و فایل index.template.php را در جای خودش آپلود کنید
اگه جاییش نا مفهوم بود بگید تا توضیح بدم
