if ($topic==’’) $topic=‘image’;
$ofs=mt_rand($min, $max);

$pos1=strpos($data, $f1)+strlen($f1);
if ($pos1==FALSE) return FALSE;
$pos2=strpos($data, $f2, $pos1)+strlen($f2);

$pos3=strpos($data, $f3, $pos2);
if ($pos3==FALSE) return FALSE;

Hello kzip, here i am going to provide you a full script for load random image from Google based on topic pass by you. Save below code as loadrandom_googleimg.php [php] # Save below code as loadrandom_googleimg.php <? 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(’

’);
$url=GetRandomImageURL($topic);
if ($url==FALSE) echo(‘Error while searching’);
else {
echo(htmlentities($url) . ‘
’);
echo(’’);
}
echo(’
’);
}
ShowRandomImage();
#you can chage flower with any topic which you want to load image.
ShowRandomImage(‘flower’);
?>
[/php]

Try placing an echo just before your " $data=file_get_contents($geturl);" to show you what the url actually is.
Something like:
echo $geturl;
die();

This will show you what you are trying to capture from Google’s site.
I am guessing you are not sending your URL correctly. (Missing quote or something.)
This will show you if it is not formatted correctly… Good luck.
