free Flickr User with Flickr Gallery Plugin

Realizing having a lazy gallery plugin, in which all photos are stored on my server, I decided to try the Flickr Gallery plugin from https://www.worrad.com/archives/2005/01/08/flickr-gallery-07/, which looks good and saves my server space.

I followed the instructions at the readme.txt file, the one at worrad.com, and also https://www.nicemess.com/?p=4 , and in the end, when i type https://www.xxxxx.com/blog/gallery.php, the following showed up:

Parse error: parse error, unexpected ‘/’ in /home/seville/public_html/blog/gallery.php on line 3

It was painful to set up, so I just wanna make a check list to see if anything is missing?
-make a photset in my flickr.
-download the zip file and and change the settings flickr-gallery.php and upload it to the plugin directory
-create a gallery.php file with the following codes and upload it to the /wp-content/themes/default/ directory
<?php get_header(); ?>
<div id=a€?contenta€? class=a€?narrowcolumna€?>
<?php flickr_show_photos($_GET[a€?albuma€?], $_GET[a€?photoa€?]); ?>
</div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>

-create another gallery.php with the following codes and upload it to the root directory where I stored my blog.
<?php
$_SERVER[a€?PATH_INFOa€?] = a€?a€?;
require(a€?./wp-blog-header.phpa€?);
include(TEMPLATEPATH . a€?/gallery.phpa€?);
?>
-upload the annimg.js file to my root directory where I stored my blog.
-create a folder call flickr-cache under my wp-content directory

As for the CSS, I use the default, is there anything I missed? Would appreciate if anyone could point out my mistake. Thanks a lot in advance. ??
