     65= 2.0 =
     66* security - image resizing utility can be called internally using post id instead of independent url. So noone else can use your bandwidth.
     67* caching - It caches first image url of all posts and tagged with post itself to save runtime processing.
     68* filesystem - Now it caches resized images on your site itself. It saves repeated on the fly resizing thus high CPU and memory.

     65= 2.0 =
     66* security - image resizing utility can be called internally using post id instead of independent url. So noone else can use your bandwidth.
     67* caching - It caches first image url of all posts and tagged with post itself to save runtime processing.
     68* filesystem - Now it caches resized images on your site itself. It saves repeated on the fly resizing thus high CPU and memory.
