script de carrocel simples

[arldin]

Não sei se estou postamdo no lugar certo

Este e um script simples de carrocel de imagem

<script type=text/javascript>
// 7 variables to control behavior
    var Car_Image_Width=111;
    var Car_Image_Height=121;
    var Car_Border=true;        // true or false
    var Car_Border_Color="0000ff";
    var Car_Speed=5;
    var Car_Direction=true;        // true or false
    var Car_NoOfSides=8;        // must be 4, 6, 8 or 12

/* array to specify images and optional links. 
    For 4 sided carousel specify at least 2 images
    For 6 sided carousel specify at least 3
    For 8 sided carousel specify at least 4
    For 12 sided carousel specify at least 6
 If Link is not needed keep it ""
