Use this modified script and modify the parts in red accordingly:

var seqslides=new Array()
//Set Path to Image plus optional URL ("" for no URL):
//the 3rd item is the alt and the 4th are the title, modify accordingly
seqslides[0]=["image1.gif", "http://www.dynamicdrive.com", "alt1", "title1"]
seqslides[1]=["image2.gif", "http://www.javascriptkit.com", "alt1", "title1"]

seqslides[4]=["image5.gif", "http://www.google.com", "alt1", "title1"]

//Set pause between each image display (2000=2 second):
var slidedelay=2000

//Set how many images to show at once (must be less than total # of images above):
var slidestoreveal=3

//Specify code to insert between each slide (ie: "<br>" to insert a line break and create a vertical layout)
//"" for none (or horizontal):

//Set image border width:
var imgborderwidth=0

//Set opacity value of each image when it's "dimmed", and when it's not, respectively (1=100% opaque/normal).

Thanks, but cannot get this new script to work.

With original script was as able to change this line only to (from a previous post) :


imghtml+='<img src="'+theimg[0]+'" border="'+imgborderwidth+'" style="filter:alpha(opacity='+(opacityvalues[0]*100)+');-moz-opacity:'+opacityvalues[0]+'" title="'+theimg[2]+'">'

This works for title tag, but I can't figure out what to add to get "alt" tag to work.

Thank you, but I cannot get this to work.

I was able to get "title" tag to work by making this change (from another post) and changing "alt" to "title".

imghtml+='<img src="'+theimg[0]+'" border="'+imgborderwidth+'" style="filter:alpha(opacity='+(opacityvalues[0]*100)+');-moz-opacity:'+opacityvalues[0]+'" alt="'+theimg[2]+'">'

Since I have lots of images and "title" tags already in place, would like to just update this line if possible.

I think this is working:

imghtml+='<img src="'+theimg[0]+'" border="'+imgborderwidth+'" style="filter:alpha(opacity='+(opacityvalues[0]*100)+');-moz-opacity:'+opacityvalues[0]+'" alt="'+theimg[2]+'"title="'+theimg[3]+'">'

How are you trying the updated script? It's working fine for me.
