This is what the website creator, a friend said he'd used for the flikr pictures/search. I'd like the same for teachers creating the baam game questions if possible...


I used phpFlickr http://phpflickr.com/ to provide the interface. Really easy. Here is the php that handles queries coming from the javascript code that implements the wizard.

/* handle query callbacks from the page */
$query = getGet('query', false);
if($query) {
   $page = getGet('page', 1);
   require_once("phpFlickr/phpFlickr.php");
   $flickr = new phpFlickr("d205ff3d86bf230a2c093eef0211280a");
   $flickr_results = $flickr->photos_search(array(
      "tags"=>$query,
      "tag_mode"=>'all',
      "sort"=>"interestingness-desc",
      "per_page"=>14,
      "license"=>"1,2,3,4,5,6",
      "safe_search"=>1,
      "page"=>$page));
   foreach($flickr_results['photo'] as &$photo) {
       foreach(Array('Square', 'Thumbnail', 'Small') as $size) {
           list($url, $w, $h) = localize_image($flickr->buildPhotoURL($photo, $size));
           $photo[substr($size, 0, 2)] = $url;
       }
   }
   unset($photo);

   $json = new Services_JSON();
   $output = $json->encode($flickr_results);
   header('Content-Type: application/json');
   header('Content-Size: ' . strlen($output));
   echo $output;
   die();
}

Virtually all of that is straight from the examples and API description. The one trick is that function localize_image. 
Lots of schools block access to Flickr so I had to cache the images locally so I could serve them from our URL.
