Hello All… Having issue with converting this php code from buttons to a button. What i am trying to accomplish is simple.
I want to make a folder of pictures go from pic to pic by clicking the pic to go to the next in the folder. I want to click the pic to make this happen so the pic is the button… what i have is below… which has been made to use a previous and next text button which I want to convert to be the image. I dont know how to define the image as the button… I dont need a previous button i just want the pictures to go on forever until it reaches the last file and then begin at the begging.
[code]<?php
session_start();
$dir = ‘yorkwood/images’; //<<<---- Path to your images, NO TRAILING SLASH.
if(!isset($_SESSION[‘images’])) { //If the image array IS NOT saved in sessions
if ($handle = opendir($dir)) { //Open the image directory.
while (false !== ($file = readdir($handle))) { //while there are files to read.

$parts = explode(’.’,$file); //split the file on a period.
$c = count($parts); //count the parts array.
$ext = $parts[$c-1]; //ext will reside as the last value of the array.
if(strtolower($ext) == ‘png’ || strtolower($ext) == ‘jpg’ || strtolower($ext) == ‘gif’) { //if the ext is image type.
$images[] = $file; //save it to the image array.

}
