preload images

How can I preload images in php
Thanks..

preload? do you mean by preview or something? if that is true, i think it involves more than php, because php only handles the online directories, it might work if you save them in the tmp folder or something, but this involves refreshing the page, so i doubt if this is what you want, but afterall, i am not sure...

You don't.  preloading something is a client-side thing.

I mean loading the images then showing them

as in...retrieving a list from a directory?

[code]
<?php
  $path = "path/to/images/";
 
  // if the directory exists...
  if ( $img_dir = @opendir($path) ) {
      // while there are files to read in the dir listing...
      while ( false !== ($img_file = readdir($img_dir)) ) {
        // if the mime type is .jpg (add checks for other image file types here, if you like) ...
        if ( preg_match("/(\.jpg)$/", $img_file) ) {
            // add it to list of images available
            $images[] = $img_file;
        } // end if image found
      } // end while files in dir list
  // close the dir stream
  closedir($img_dir);
  } // end if dir opened

  // if there are images to display...
  if ($images) {
      // for each image...
      foreach ($images as $img) {
        // echo image
echo "<img src = '$path$img' />";
      } // end foreach image
  } // end if images
?>
