Why does this work intermittently?
It is a page of thumbs. Click on a thumb and a display pops up allowing user to view pix in sequence by clicking a button.
the first 15 thumbs are active - numbers 0 - 14.
Sometimes it won't show any. Sometimes it will show the first 4, or the first 12, then just stop working.
You can view source to see code.
My first post, sorry if it does not conform.
