hello edward
take a look at my pmx test site:
http://pragmatest.martin-beurskens.eu/index.phpis it that, what you like? if it is, than you can use every slideshow software you'll find at the web. the only thing you have to do after you've configurated the slideshow, is to insert the given code into the header of the template and to place the pictures in the right folder.
i'm used for the slideshow on my testside comercial software. íf you want to knew, what it is, you can contact me by pm.
kind regards
martin b
