Rotating background images

Programming
Tutor: None Selected Time limit: 3 Days

Good day

I'm using a one page full background template with 3 images that rotate if you click on the buttons on the bottom of the page. I can/and want to remove these buttons, but i need help in rotating the images automatically? The template got JQUERY 1.6 with bgslidder. Any help will be appreciated.

Here are instructions on how to do it:

1.) Open up your favorite web page editor. (SOMETHING OTHER THAN A WORD PROCESSOR)

2.) Copy the below code, paste in a php format page.
Code: [Select]

ABOUT
This PHP script will randomly select an image file from a
folder of images on your webserver. You can then link to it
as you would any standard image file and you'll see a random
image each time you reload.

When you want to add or remove images from the rotation-pool,
just add or remove them from the image rotation folder.


VERSION CHANGES
Version 1.0
- Release version

Version 1.5
- Tweaked a few boring bugs

Version 2.0
- Complete rewrite from the ground-up
- Made it clearer where to make modifications
- Made it easier to specify/change the rotation-folder
- Made it easier to specify/change supported image types
- Wrote better instructions and info (you're them reading now)
- Significant speed improvements
- More error checking
- Cleaner code (albeit more PHP-specific)
- Better/faster random number generation and file-type parsing
- Added a feature where the image to display can be specified
- Added a cool feature where, if an error occurs (such as no
images being found in the specified folder) *and* you're
lucky enough to have the GD libraries compiled into PHP on
your webserver, we generate a replacement "error image" on
the fly.

Version 2.1
- Updated a potential security flaw when value-matching
filenames

Version 2.2
- Updated a few more potential security issues
- Optimized the code a bit.
- Expanded the doc for adding new mime/image types.

Thanks to faithful ALA reader Justin Greer for
lots of good tips and solid code contribution!


INSTRUCTIONS
1. Modify the $folder setting in the configuration section below.
2. Add image types if needed (most users can ignore that part).
3. Upload this file (rotate.php) to your webserver. I recommend
uploading it to the same folder as your images.
4. Link to the file as you would any normal image file, like this:

<img src="http://example.com/rotate.php">

5. You can also specify the image to display like this:

<img src="http://example.com/rotate.php?img=gorilla.jpg">

This would specify that an image named "gorilla.jpg" located
in the image-rotation folder should be displayed.

That's it, you're done.

*/




/* ------------------------- CONFIGURATION -----------------------


Set $folder to the full path to the location of your images.
For example: $folder = '/user/me/example.com/images/';
If the rotate.php file will be in the same folder as your
images then you should leave it set to $folder = '.';

*/


$folder = '.';


/*

Most users can safely ignore this part. If you're a programmer,
keep reading, if not, you're done. Go get some coffee.

If you'd like to enable additional image types other than
gif, jpg, and png, add a duplicate line to the section below
for the new image type.

Add the new file-type, single-quoted, inside brackets.

Add the mime-type to be sent to the browser, also single-quoted,
after the equal sign.

For example:

PDF Files:

$extList['pdf'] = 'application/pdf';

CSS Files:

$extList['css'] = 'text/css';

You can even serve up random HTML files:

$extList['html'] = 'text/html';
$extList['htm'] = 'text/html';

Just be sure your mime-type definition is correct!

*/

$extList = array();
$extList['gif'] = 'image/gif';
$extList['jpg'] = 'image/jpeg';
$extList['jpeg'] = 'image/jpeg';
$extList['png'] = 'image/png';


// You don't need to edit anything after this point.


// --------------------- END CONFIGURATION -----------------------

$img = null;

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

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

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

if ($img!=null) {
$imageInfo = pathinfo($img);
$contentType = 'Content-type: '.$extList[ $imageInfo['extension'] ];
header ($contentType);
readfile($img);
} else {
if ( function_exists('imagecreate') ) {
header ("Content-type: image/png");
$im = @imagecreate (100, 100)
or die ("Cannot initialize new GD image stream");
$background_color = imagecolorallocate ($im, 255, 255, 255);
$text_color = imagecolorallocate ($im, 0,0,0);
imagestring ($im, 2, 5, 5, "IMAGE ERROR", $text_color);
imagepng ($im);
imagedestroy($im);
}
}

?>

3.) Save as rotate.php

4.) Upload to your ./<dir_to_smf>/Themes/<your_theme>/images/background
If you need to make a folder called background than make one inside of Themes/<your_theme/images

5.) Upload roate.php to the new folder called background inside of your theme. Choose background images you want to randomly rotate and put them in /background/ as well. It doesn't matter what the image files are called. The only requirement is they must be one of these image formats: gif, jpg, jpeg, png

6.) Inside wherever you want the images to rotate. Probably in a table. Use a code like below:
Code: [Select]
<table background="', $settings['images_url'], '/background/rotate.php">

It should now rotate through all images inside of the background as long as you link it to the php file. This should work, and I know the code I provided works because I use it on my site for different purposes.

To test the actual rotation of the images, just run this url directly in your browser.
