//Specify the slider's width (in pixels)
var sliderwidth=300
//Specify the slider's height
var sliderheight=150
//Specify the slider's slide speed (larger is faster 1-10)
var slidespeed=3
//configure background color:
slidebgcolor="#EAEAEA"

//Specify the slider's images
var leftrightslide=new Array()
var finalslide=''
leftrightslide[0]='<a href="http://"><img src="dynamicbook1.gif" border=1></a>'

*** Question on it: How do I edit it to be positioned in the middle of the page instead of on the left side of page? (I'm sure that's an easy answer, but I'm new at this...sorry


Also, when I resize a pic in PSP 7 from ie: 300x350 pixels to 260x211, how do I get the same quality in the pic? The images turn out with scrunched faces or pixel speckles

Thanks in advance!
