Scrolling image

[Chance1234]

Using this code below from dynamicdrive

http://www.dynamicdrive.com/dynamicindex4/cmotiongallery.htm

I need to make one change to this. My images are all different sizes and I want to centre them in the scroll area. Not very familiar with Java script so help much appreciated.

var restarea=3 //1) width of the "neutral" area in the center of the gallery in px
var maxspeed=200 //2) top scroll speed in pixels. Script auto creates a range from 0 to top speed.
var endofgallerymsg="<span style='font-size: 11px'>End of Gallery</span>" //3) message to show at end of gallery. Enter "" to disable message.

function enlargeimage(path, optWidth, optHeight){ //function to enlarge image. Change as desired.
var actualWidth=typeof optWidth!="undefined" ? optWidth : "600px" //set 600px to default width
var actualHeight=typeof optHeight!="undefined" ? optHeight : "500px" //set 500px to  default height
var winattributes="width="+actualWidth+",height="+actualHeight+",resizable=yes"
window.open(path,"", winattributes)
}
