<?php
/*
Images.txt is a text file which can have any number of text lines like Quotable quotes, a URL, address of a graphics file or even a code segment etc.to be randomly selected. Of course if the file is not in the same directory, correct path to be provided (sorry for the obvious sermon :) ).
You can edit Images.txt by adding deleting items as you wish. No more hard coding those damned Javascript arrays (YUCK!. It doesnt matter if there are 10 or 100 items - the code doesnt change as it dynamically selects the random item out of any number........wow
The $buffer at the end will have the magic random stuff that you can shove in any thing you want. YIKES!
I have just given an example and will come up with more in near future.
I have used some DHTML stuff in the example just for the heck of it. Its not a must. Thats why the need for 4.x browsers. But I guess all of you guys would have it.
