$dir = exec('pwd');
$open_dir = opendir("$dir");
//Add or remove files extensions to suit your needs. //Notice that the extensions are in upper and lower case. $image_ext_array = array( "jpg", "jpeg", "gif", "png",
//If the PHP server is less that 4.2.0 the SRAND function is needed. //srand((float) microtime() * 10000000); $show_img = array_rand($image_files);
//Optional: use the HEADER function to prevent the browser from caching the html content and image. //This is most use full when using the HEADER function to display the image //header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); //header ("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); //header ("Cache-Control: no-cache, no-store, must-revalidate, private, max-age=0, proxy-revalidate, no-transform"); //header ("Pragma: no-cache"); //header("Vary: User-Agents");
//Edit the image ALT field to suit your needs. $image_alt = "FreshSoftware 1-866-343-3343";
//USE the ECHO function to display HTML Code. //echo "<img src=\"$image_files[$show_img]\" width=\"$image_width[0]\" height=\"$image_height[1]\" alt=\"$image_alt\">";
//The HEADER function often times fails to rotate an image when refreshing a browser. //header("location: http://freshsoftware-internal.net/images/advertisments/freshsoftware/$image_files[$show_img]");
//Recommended. These three lines make use of the FPASSTHRUE function. $open_image = fopen($image_location, 'rb'); fpassthru($open_image); fclose($open_image);
