This is not an easy thing to do but it can be done :) Jay ----- Original Message ----- From: "Andy Woolley" <andy@milonic.com> To: "Jason Lavigne" <jlavigne@stonecroft.net>; "Miles Thompson" <milesthompson@sprint.ca>; <murph@murphatnight.com> Cc: <php-general@lists.php.net> Sent: Friday, December 08, 2000 8:03 AM Subject: Re: [PHP] Progress bar? > Guys, > > I think that this is being a little too complicated. > > In the past I used Layers, though not supported in NS6 and most importantly > the DOM, to display a portion of the page with an animated "scrolling bar" > gif. > > ie.
