如何在一个请求中为特定用户的每个Flickr标签获取一张照片?

基本上我正在做的是生成缩略图页面.指定用户具有的每个标签都有一个缩略图.因此，如果用户使用了50个不同的标签，则将有50个缩略图(我将最终对其进行分页.).有用;这只是效率低下.即使只有8个标签，这也非常慢，因为它必须等待Flickr服务器的9个响应(标签列表为+1).有没有更有效的方法可以做到这一点?扫描Flickr API时似乎找不到更好的解决方案.以下是我目前正在执行的操作.

Basically what I am doing is generating a page of thumbnails. There is one thumbnail for each tag that the specified user has. So if the user has used 50 different tags there will be 50 thumbnails (I'll eventually paginate this.). It works; it's just inefficient. Even with just 8 tags, this is very slow since it has to wait for 9 responses (+1 for the list of tags) from the Flickr servers. Is there a more efficient way to do this? I can't seem to find a better solution whilst scanning the Flickr APIs. Below is what I am currently using to do this.

<?php   
    function get_api_url($additional_params) {
        $params = array_merge($additional_params, array(
            'api_key'   => API_KEY,
            'format'    => 'php_serial',
            'user_id'   => USER_ID,
        ));

        $encoded_params = array();
        foreach ($params as $k => $v)
            $encoded_params[] = urlencode($k) . '=' . urlencode($v);

        return 'http://api.flickr.com/services/rest/?' . implode('&', $encoded_params);
    }

    // Set any additional paramaters.
    $additional_params = array(
        'method'    => 'flickr.tags.getListUser',
    );

    // Get the tags.
    $rsp_obj = unserialize(file_get_contents(get_api_url($additional_params))); 

    // Parse the tags.
    $unparsed_tags = $rsp_obj['who']['tags']['tag'];
    $tags = array();
    foreach ($unparsed_tags as $tag) {
        $tags[] = $tag['_content'];
    }

    // Set any additional parameters.
    $additional_params = array(
        'method'    => 'flickr.photos.search',
        'per_page'  => '1',
    );
    $api_url = get_api_url($additional_params);

    // Call the API and parse the response.
    echo "<div id=\"tags\">";
    foreach ($tags as $tag) {
        $rsp_obj = unserialize(file_get_contents($api_url . '&tags=' . urlencode($tag)));
        $photo = $rsp_obj['photos']['photo'][0];

        $image_url = 'http://farm' . $photo['farm'] . '.static.flickr.com/' .
            $photo['server'] . '/' . $photo['id'] . '_' . $photo['secret'] . '_m.jpg';
        $tag_url = "/gallery/?tag=$tag";
        $tag = ucwords($tag);
        echo <<<HD
            <a class="tag" href="$tag_url">
                <img src="$image_url" />
                <span class="caption">$tag</span>
            </a>
HD;
    }
    echo '</div>';
