Hej

Jeg har taget dette script og lagt ind på en hjemmeside.
http://www.dynamicdrive.com/dynamicindex14/leftrightslide2.htm

Det fungere sådan set også, men hvis der er mindre end 3 slides altså 2. Så gå den videre til at sige at efter nummer 2 er de undefined.

Mit kode:
        <script language="JavaScript1.2">

///////configure the below four variables to change the style of the slider///////
//set the scrollerwidth and scrollerheight to the width/height of the LARGEST image in your slideshow!
var scrollerwidth='100px'
var scrollerheight='100px'
var scrollerbgcolor='#FF0000'
//3000 miliseconds=3 seconds
var pausebetweenimages=1000
//configure the below variable to change the images used in the slideshow. If you wish the images to be clickable, simply wrap the images with the appropriate <a> tag
var slideimages=new Array()
slideimages[0]='<P>Ugens tilbud:<BR>5 kilo flæsk.
