Displaying google images on my website? (revised)

问题

so basically I'm trying to display images on my website from google images based on a word stored in an array. Right now, I have this simple PHP code that loads in my .txt file, puts a random word into the $lines array, and then picks a random word from it.

<?php $lines = file('things.txt');
echo $lines[array_rand($lines)];
?>

and then I have this code, directly from google, that does an image search for a particular word specified in the code and then displays the results onto your webpage.

<script src="https://www.google.com/jsapi"></script>
    <script type="text/javascript">

      google.load('search', '1');

      var imageSearch;

      function addPaginationLinks() {

        // To paginate search results, use the cursor function.
        var cursor = imageSearch.cursor;
        var curPage = cursor.currentPageIndex; // check what page the app is on
        var pagesDiv = document.createElement('div');
        for (var i = 0; i < cursor.pages.length; i++) {
          var page = cursor.pages[i];
          if (curPage == i) { 

          // If we are on the current page, then don't make a link.
            var label = document.createTextNode(' ' + page.label + ' ');
            pagesDiv.appendChild(label);
          } else {

            // Create links to other pages using gotoPage() on the searcher.
            var link = document.createElement('a');
            link.href="/image-search/v1/javascript:imageSearch.gotoPage("+i+');';
            link.innerHTML = page.label;
            link.style.marginRight = '2px';
            pagesDiv.appendChild(link);
          }
        }

        var contentDiv = document.getElementById('content');
        contentDiv.appendChild(pagesDiv);
      }

      function searchComplete() {

        // Check that we got results
        if (imageSearch.results && imageSearch.results.length > 0) {

          // Grab our content div, clear it.
          var contentDiv = document.getElementById('content');
          contentDiv.innerHTML = '';

          // Loop through our results, printing them to the page.
          var results = imageSearch.results;
          for (var i = 0; i < results.length; i++) {
            // For each result write it's title and image to the screen
            var result = results[i];
            var imgContainer = document.createElement('div');
            var title = document.createElement('div');

            // We use titleNoFormatting so that no HTML tags are left in the 
            // title
            title.innerHTML = result.titleNoFormatting;
            var newImg = document.createElement('img');

            // There is also a result.url property which has the escaped version
            newImg.src="/image-search/v1/result.tbUrl;"
            imgContainer.appendChild(title);
            imgContainer.appendChild(newImg);

            // Put our title + image in the content
            contentDiv.appendChild(imgContainer);
          }

          // Now add links to additional pages of search results.
          addPaginationLinks(imageSearch);
        }
      }

      function OnLoad() {

        // Create an Image Search instance.
        imageSearch = new google.search.ImageSearch();

        // Set searchComplete as the callback function when a search is 
        // complete.  The imageSearch object will have results in it.
        imageSearch.setSearchCompleteCallback(this, searchComplete, null);

        // The Term to Search, I want this to be the random word generated in the $lines array
        imageSearch.execute("pickles");

        // Include the required Google branding
        google.search.Search.getBranding('branding');
      }
      google.setOnLoadCallback(OnLoad);
    </script>

Now I cannot figure out for the life of me how to make that code above do a search based on the random word my php code generated earlier. I've tried various ways but I'm just not experienced enough with coding to try and figure this one out on my own.

hope this one makes sense, thanks guys
