Display Random Images Script - Image Rotation Code Pictures PHP Rotate HTML by braker

One of the many things you can do to make your website less boring is to display your visitors a different image everytime they visit your pages. You can do this PHP. While you can also do this with javascript, in this tutorial guide, i will show you how to generate random images and display them on your webpages using PHP.

The only requirement for this to work on your web pages is that you have PHP in your hosting. IF you don't have php, you can signup with www.webune.com for a php plan. if you have php, continue on...

the first thing i tell you to do is to open a text editor like notepad and transfer this code into a blank document:

Code:

<?php
$image_directory = '.';
$image_extension = array();
$image_extension['gif'] = 'image/gif';
$image_extension['jpg'] = 'image/jpeg';
$image_extension['jpeg'] = 'image/jpeg';
$image_extension['png'] = 'image/png';

$image = null;
if (substr($image_directory,-1) != '/') {
$image_directory = $image_directory.'/';
}

if (isset($_GET['image'])) {
$img_info = pathinfo($_GET['image']);
if (
isset( $image_extension[ strtolower( $img_info['extension'] ) ] ) &&
file_exists( $image_directory.$img_info['basename'] )
) {
$image = $image_directory.$img_info['basename'];
}
} else {
$fileList = array();
$handle = opendir($image_directory);
while ( false !== ( $file = readdir($handle) ) ) {
$file_info = pathinfo($file);
if (
isset( $image_extension[ strtolower( $file_info['extension'] ) ] )
) {
$fileList[] = $file;
}
}
closedir($handle);

if (count($fileList) > 0) {
$imageNumber = time() % count($fileList);
$image = $image_directory.$fileList[$imageNumber];
}
}

if ($image!=null) {
$img_info = pathinfo($image);
$contents = 'Content-type: '.$image_extension[ $img_info['extension'] ];
header ($contents);
readfile($image);
} else {
if ( function_exists('imagecreate') ) {
header ("Content-type: image/png");
$picture = @imagecreate (100, 100)
or die ("Cannot initialize new GD image stream");
$bgcolor = imagecolorallocate ($picture, 255, 255, 255);
$font_color = imagecolorallocate ($picture, 0,0,0);
imagestring ($picture, 2, 5, 5, "IMAGE ERROR", $font_color);
imagepng ($picture);
imagedestroy($picture);
}
}
?>

this code will generate a random image for you. this is you can say the engine that makes it all work. now that you have transfered the code into notepad, you can save it as: wallpaperama-generator.php

once you haved samed it in your computer, then upload to your site. Remember, you must have php for this script to work, if you dont' have php yet, get a host who offers PHP. www.webune.com offers PHP Web hosting, check them out.

not all you have to do is to put this tag on whatever page you want to display the random images on a certain directory:

Code:

that's all the time i have right now. hope i helped you
