# if (($file !=".") && ($file !="..") && (substr($file, -10) == ".thumb.jpg"))

I use a coppermine gallery inside a ezcontents portal and displaying images on different pages with Coppermine is a bit of a task. (coppermine prefixes to identify thumbs) Your script would ideally suit me if it could filter accordingly.

regards

- Create a (super)array
- Let the script browse the directories and add the image names to this array.
- Pick randomly from the array.

How?

# Relative to current directory
$imgdir = 'random/image/directory/';
$dir = $_SERVER['DOCUMENT_ROOT'] . '/' . $imgdir;
$images = array();
#
# The user doesn't need to see any errors
$dir_handle = @opendir($dir);
#
# The correct way to iterate over a directory
# (see http://www.php.net/manual/en/function.readdir.php)
while (false !== ($file = readdir($dir_handle)))
  if (!is_dir($file))
    $images[] = "$file";
#
closedir ($dir_handle);
#
# The following appears to make things "more" random
srand((double)microtime()*1000000);
$r = rand(0,sizeof($images)-1);
#
echo "<img src=\"{$imgdir}{$images[$r]}\">";

There is at least one caveat that I know about - images must exist in one directory with no sub directories. Theoretically, this shouldn't be a problem, but I've had problems with the script when trying to run it in a directory with subdirectories.

and each sub fold has images in them . This is annoying me as i have different sub folders in my main images folder and this script doesn't work !

Here are the details:

Save the script as randimg.php.. I have discovered iframes which seem to do the trick.. Add the iframe tag to the textsettings.php file in conf dir of phpwebsite. Add the following to the block content:
<iframe marginwidth="0" marginheight="0" width="180" scrolling="no" frameborder=0 src="randimg.php"></iframe>
