This version, (and in fact FlickArray as a whole), has been discontinued in favour of the Flickr library written for CodeIgniter, discussed in more detail in this article.
While building flickrShow I also made updates to the flickArray class. I added support for photosets and have updated method and variable names to make them more readable and logical. I am in the process of rebuilding it in PHP 5 to make use of the new XML and OOP functionality, which should speed it up somewhat and allow it to be extended in a logical fashion.
