I apologize for presenting you with such a mess.
I have cleaned up the distractions.
I am using Dreamweaver MX 2004 - and both pages show no html errors.
My question was;
One page will show an image when a thumbnail is clicked, whether they match - a larger image will appear. That is on wc1.htm
On wc2.htm, not picture appears at all.
thanks for your help. It is appreciated.
