Google Images Grabber - need help

[jsschmitt]

The following code works, except that it is always throwing a chunk of code into an image tag at the beginning.

 

I can't figure out how to filter out that chunk of code.

 

Try for yourself: http://anomymage.com/tests/do/search/

 

<form name="input" action="./" method="get">
Search:
<input type="text" name="string" />
<input type="Submit" value="Go" />
</form> 

<?php

function google_image ($q)
{
  $q_filter = "*.*";
  $q = str_replace ( " " , "+", $q );
  $get_data = file_get_contents ("http://images.google.com/images?q=".$q . "+" . $q_filter . "&imgsz=small|medium|large|xlarge&hl=en&sa=G&safe=off&gbv=1");
  $exp1 = explode ( "http://tbn", $get_data );
  
  $images = array();
  
  foreach ($exp1 as $exp)
  {
   $exp2 = explode ( "width", $exp );
   $images[] = "http://tbn" . $exp2[0];
  }
  
  return $images;
}

$search = $_GET['string'];

$images = google_image ($search);
foreach ($images as $image)
{
   echo "<img src='$image'>\n";
}

?>

 

Also, if anyone has any idea on how to increase the number of images shown, that would be fantastic ^.^

No one knows anything?

Firstly, the link you posted doesn't run that script. Where does the "Full Size" link text come from? And I have absolutely no idea how exploding at "width" to get the last part of the image URLs could work.

 

I would grab the images with something like this:

 

<?php
function google_images($q, $page) {
$q = urlencode($q);
$start = ($page - 1) * 21;
$get_data = file_get_contents("http://images.google.com/images?q=$q&hl=en&safe=off&imgsz=small|medium|large|xlarge&start=$start");
preg_match_all('~/imgres.+?"","([^:]+","([^"]+)".+?(http://tbn[^"]+)"~is', $get_data, $matches, PREG_SET_ORDER);
$images = array();
foreach ($matches as $data) {
	$images[] = array(
		'thumb' => $data[3] . '?q=tbn:' . $data[1] . $data[2],
		'original' => $data[2]
	);
}
return $images;
}
echo '<pre>' . print_r(google_images('test', 1), true) . '</pre>';
?>

 

I added a page variable to the function, so you're not stuck with the images on page one only. You know it's only searching medium sized images, right?

 

And my God, Google's source code is f**ked up. Didn't keep me from grabbing the URLs though

Don't know about Images, but on Maps they're pretty good at blocking bots.

Ok... to show my noob-ness. How would I go about echoing out each portion of the array?

[jsschmitt]

Wait... figured it out ^.^
