Fixing Flickr FAlbum rewrite rules, thumbnails, javascripts and more …

This is not working anymore

FAlbum is a WordPress Plug-in that adds your Flickr photo albums to your blog without redirecting the viewer to Flickr or leaving your blog. It is very useful and unique, I have always needed that plugin on my blog, however, some features needed a lot of digging into the code to fix or to get it working. So, I am going to describe a step by step installation of this plugin then will show how to fix.
