More on my Church Web Page redo:
It's nice to have a picture on the front page, showing the church, or, more importantly, the people who make up the church. It's even nicer to have the picture change occasionally.
The ideal way to do this is to make a Flash slideshow, something easily accomplished with SWFTools, available in fine Linux distributions everywhere. It's fairly simple: Load up all the pictures in order, and export the file, possibly making a political statement everyone in the Universe will ignore. ahem Sorry, some things die hard.
The advantage of Flash is that everything is loaded into your visitors browser once, and then stays there, rotating pictures, for as long as she/he is on the page.
The disadvantage, at least with the method used here, is that the pictures are always in the same order. Which means that the casual visitor, who only stays on your site for maybe 60 seconds at a time, will only get a few pictures, always in the same order.
Not to mention, every time you add or subtract a picture from the lineup, you've got to recompile the animation — not an onerous task, but an annoyance.
PHP can solve part of this problem.
