Need my forum background picture to change on refresh
Hey I am wanting to use this theme: https://vborg.vbsupport.ru/showthread.php?t=259252
But with my own background pictures. How do I make it change between pictures every time a new page is opened or the page is refreshed? EDIT: Also how do i make it so when you scroll down and up the picture scroll with you.

I'll have to assume you used the stylevar for the background and parked your image there. On the right of the right hand ) put a space and add the word fixed. Save. That pins the image down and lets the forum scroll over it.
This code is a rotator I found out on the net several years ago and it works just fine. Code:

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);
}
}
?>
Make a folder and drop your images in it along with that file. Remember the path to the folder. Go to the stylevar background you are going to use and put the url in in this format > url(path/to/your/folder/rotate.php) fixed Now when you jump from page to page, click the logo, or refresh the browser, the rotator will randomly pick an image and show it. Check out the forum sidebar at my place to see it in action. www.animeappeal.com

The full url is "url(/images/bf3/BF3 Backgrounds/rotate.php) fixed" "bf3" is the theme folder, where all the files for the theme are. "BF3 Backgrounds" is a folder I made inside the theme folder and I put all my background images in there including the rotate.php. The images are .jpg but one is .png is that why it might not work? EDIT: I tried making it "url(/images/bf3/BF3 Backgrounds/Crysis.jpeg) fixed". So it would link straight to an image. Even that didn't work. What has gone wrong?

But when I add "fixed" at the end with a space it makes the images disappear again. Is that the only way to make the picture move whilst you scroll? EDIT: I found out how to fix it. I had to put "fixed" in "Background Image Vertically Offset" field, and not after the url. Problems solved thanks guys
