<?php

// outputs e.g.  somefile.txt: 1024 bytes

$filename = 'somefile.txt';
echo $filename . ': ' . filesize($filename) . ' bytes';

?>

$size = getimagesize("$photo");

$height = $size[1];

$width = $size[0];

if ($height<=$width){ print "<img width='120' src='$photo'>"; } else { print "<img height='100' src='$photo'>"; }

 

why this code works so slow ?

Is the file local? I know when considering the GD library and images in general with PHP has some problems when trying to get images from non-local machines.

If you are in fact using an older version of PHP (4.0 or earlier) you'll definitely have problems. Try this code that was directly from PHP.net, it might not be the best but it should work as a more manual way of getting information about a remote file:

function getimagesize_remote($image_url) {
    $handle = fopen ($image_url, "rb");
    $contents = "";
    if ($handle) {
    do {
        $count += 1;
        $data = fread($handle, 8192);
        if (strlen($data) == 0) {
            break;
       }
    $contents .= $data;
    } while(true);
    } else { return false; }
    fclose ($handle);

    $im = ImageCreateFromString($contents);
    if (!$im) { return false; }
    $gis[0] = ImageSX($im);
    $gis[1] = ImageSY($im);
    // array member 3 is used below to keep with current getimagesize standards
    $gis[3] = "width={$gis[0]} height={$gis[1]}";
    ImageDestroy($im);
    return $gis;
}

 

Another option is to do what I do, create another script on the server that houses the images, that script is just a function that can either manipulate an image and cache it or just return the image information.
