Re: Dynamically Rename Images

Is it possible to rename images dynamically? Say that I had something like image1.png, and I don't want to rename it on the server. I'm working on an image rotater for a forum that doesn't allow anything but image files as signatures. Here's my code so far: <?php //LolRotator //add images. not too hard. $images = array("image1.png", "image2.png", "image3.png"); //which one do we gets? $show = rand(0, (count($images)-1)); //i r got u picture. echo '<img src="'.$images[$show].'"/>'; ?> I used mod_rewrite, which makes it from image.php to image.png. But, because the files aren't named image.png, it doesn't work. I need to figure out somethign between lines 8 and 10 to change the file name to image.png.

Use mod_rewrite so that request for image.png is handled by a script, image.php image.php then randomly picks a image file from list, sends the appropriate image header, and reads the file sending the content to the browser. IE - function sendimage($impath) { // requires fedora rpm : php-pecl-Fileinfo $fi = new finfo(FILEINFO_MIME); $mime_type = $fi->buffer(file_get_contents($impath)); $imageOutput = ""; if ($fp = fopen( $impath , 'rb' )) {

    while ($l = fgets($fp)) {
      $imageOutput .= $l;
      }
    $outputLen = strlen($imageOutput);
    header("Content-Length: $outputLen");
    header("Content-type: $mime_type");
    print $imageOutput;
    } else {
    // for whatever reason we failed
    die();
    }

}

Is there a way to do this?
