Çok Güzel Javascript Ama... ?

Selamün aleyküm arkadaşlar. Ben bir okul sitesi için çalışmalara başladım. Araştırmalarım sonucunda bazı şeyler buldum. Elimde 4 adet 832 X 250 pixel boyutunda logo var. Bunlar sırasıylar ayarlandığı saniyede sola doğru kayıyor. Yani kodun yaptığı işbu. Ama kod 430 X 70 pixel için ayarlanmış. Ben uğraştım faka yapamadım lütfen bir yardım edin. Kodlar veriyorum.

Kod: Linkleri goruntulemenize izin verilmiyor. Kayit olun veya Giris yapin

<!-- STEP TWO: Insert the onLoad event handler into your BODY tag  -->

<BODY onLoad="initVar(); moveBanner()">

<!-- STEP THREE: Copy this code into the BODY of your HTML document  -->
