"a) I had already seen it - you must be a very patient person!" It's all about cut and paste for me. and the secret was originally giving each image a name that had a project designator and a number reflecting the order i wanted it to appear in the sequence. Then when I created the "Prev/Next" links, I copied and pasted and only had to change the number each time. so my code for the image titled "jessica 14" looked like:
<td align="left"><a href="http://interchangeproductions.org/documentary-photography/jessica/jessica13/">PREV
<td align="center">© 2002 Rebecca Parrish</td>
<td align="right"><a href="http://interchangeproductions.org/documentary-photography/jessica/jessica15/">NEXT</a> </td>
and I only had to go in and change the numbers of the images coming before and after for "PREV" and "NEXT" respectively. After I was finished with that. I went in and re-named each image since the image names show up in my theme. I gave the images names that where more like captions to suit my liking.
Hope I'm making sense... It was a handy trick so I thought I'd share.
