Hi Dan I use a few jQuery snippets to do things like that - One that I use a lot since its very tiny and easy to impliment is:
lite/
I also use another which scrolls a list of my products from right to left continuesly through a recordset :)
heres a demo of both in action on current project:
this shows the fading in effect (the writing in the banner)
index.php
and this shows scrolling products from a recordset:
products.php?Categories=1&WADbSearch1=GO
if you like I can provide you with the code for the jQuery - it was free code I found so its not breaking any copyright laws :)
as long as WebAssist dont mind me attaching files for other users - I guess I need to read the terms and conditions of this forum first :)
