I fixed the cache bug in the component and added a new feature to the bot_flickr4j_photo plugin. If you write id="random" it displays a random photo.

For those who have problems with the PEAR libraries. Try the following: Comment the following line out:
// ini_set('include_path', ini_get('include_path') . $path_delimiter . dirname(__FILE__) . '/PEAR'); Uncomment the following line:
ini_set('include_path', dirname(__FILE__) . '/PEAR' . $path_delimiter . ini_get('include_path'));
