Not neccessary... This problem has been driving me batty, but now it's
SOLVED!

I should have thought of the fact that this was initially a Template Monster Template. I opened up the page templates/tpl_product_info_display.php and was able to find the line of code for additional images.

The folks at Template Monster had commented that line of code to ensure that their layout would look good... not necessarily work well!

Now all I have to do is figure out how to move the thumbnail image closer to the main image display...

KOBRA, thanks for all your help here and throughout my other posts. It's greatly appreciated.
