Jim,
Code looks extremely promising & well explained - let me give it a try and
work it out. I'm sure to hit snags - but can't thank you enough.
The one thing that comes straight off in my mind looking at the code is -
and I may be addressing this prematurely since I haven't tried the code yet
- but my thumbnails are in a Separate .php page, and each thumbnail links to
the full image which are in a Separate .php page.
The Next & Previous link I'm trying to create are to be displayed on the
full image page.
But let me integrate the code and see how I can pass the values along to
pages and make it work.
Thanks again!
