   Hey guys, I really need some help figuring this out.

   I would like to randomly select an image from a folder within my theme. I have a custom function in the functions.php which makes the call and echoes the correct html code.

   This is what the function looks like:

   $path = "wp-content/themes/white/imgs/header/";
   
   $images = glob($path."*.{jpg,png,gif}", GLOB_BRACE);
   shuffle($images);
   
   echo "<img src='".$images[0]."'>";

   The problem is that when using permalinks like http://www.example.com/products/something the relative path given in the function won't work. Is there some built in functionality for solving this problem?

   I was thinking about sending the current URL when calling the function. And from there figure out how to write the relative path including the number of "../" it takes to get it right.

   Anyone?

   I am well aware of those functions, and I did try to use them.

   Is this a misunderstanding, or is it not allowed to put absolute paths like "http://www.google.com/something/whatever/*" in the glob pattern?

   glob is for searching path name - not urls.

   Yeah ok. So how would you go about and do it?

   I store the pictures in "imgs/header" inside the theme folder.
   Is there another approach then using glob for this?

   $path = get_stylesheet_directory() . "/imgs/header/";

   Yeah I did try that.

   The problem is that get_stylesheet_directory() returns this value: "/customers/antonniklasson.se/antonniklasson.se/httpd.www/code/wordpress/wp-content/themes/white"

   And that does not work well with the permalinks and so on...

   AntonNiklasson: Did you ever find a solution to this?

   I am trying to add a hardcoded fetch image in directory thing in one of my templates, and

   <?php $files = glob(ABSPATH. "wp-content/uploads/coverflow/*.*");
   for ($i=1; $i<count($files); $i++)
   {
   	$num = $files[$i];
   	echo '<li><div class="item"><img src="'.$num.'" height="100px" width="100px" /></div></li>';} ?>

   I get placeholders for the images, but the url to each image reads as: <http://www.sitename.com/home/username/public_html/wp-content/uploads/coverflow/image.jpg>

   How can I edit this to be my constant url?
   i.e :<http://www.sitename.com/wp-content/..>

   Ok! I got it to work, for my need atleast:

   <?php $img = glob("wp-content/uploads/coverflow/*.jpg");
   for ($i=1; $i<count($img); $i++)
   {	$num = $img[$i];
   	echo '<li><div class="item"><img src="http://www.siteurl.com/'.$num.'" height="75px" width="75px" /></div></li>';} ?>

   Now what I would like is to implement a preloader of all the images within this php markup...
