<?
function GetRandomImageURL($topic='', $min=0, $max=100)
  {
    // get random image from Google
    if ($topic=='') $topic='image';
    $ofs=mt_rand($min, $max);
    $geturl='http://www.google.com/images?q=' . $topic . '&start=' . $ofs . '&gbv=1';
    $data=file_get_contents($geturl);

    $f1='<div id="center_col">';
    $f2='<a href="/imgres?imgurl=';
    $f3='&amp;imgrefurl=';

    $pos1=strpos($data, $f1)+strlen($f1);
    if ($pos1==FALSE) return FALSE;
    $pos2=strpos($data, $f2, $pos1)+strlen($f2);
    if ($pos2==FALSE) return FALSE;
    $pos3=strpos($data, $f3, $pos2);
    if ($pos3==FALSE) return FALSE;
    return substr($data, $pos2, $pos3-$pos2);
  }


  function ShowRandomImage($topic='')
  {
    echo('<table border="1"><tr><td>');
    $url=GetRandomImageURL($topic);
    if ($url==FALSE) echo('Error while searching');
    else {
      echo(htmlentities($url) . '<br />');
      echo('<img width="500" src="' . $url . '" />');
    }
    echo('</td></tr></table>');
  }

  ShowRandomImage();
#you can chage flower with any topic which you want to load image.
  ShowRandomImage('flower');
?>

Thank you for your help and time in advance.

    Welcome to Stack Overflow. "It doesn't work" is *never* a good error description. Please describe what goes wrong, what error messages you get, etc. – Pekka Feb 25 '12 at 21:36
  • Can I recomend you actually parse the HTML rather than splitting it up with parameters that may quickly become outdated. – j_mcnally Feb 25 '12 at 21:41

    Read the error log: `file_get_contents` is not allowed to connect to other hosts (as `http://` in front of URLs is forbidden). The code is working for me, so editing your PHP configuration will solve the problem. – Chris Feb 25 '12 at 21:41
  • PHP safe mode, use something like libcurl or Snoopy. – j_mcnally Feb 25 '12 at 21:42
