Info
I have never been a big fan of JavaScript but recently discovered Google's AngularJS Library...

I was intrigued at a particular feature that made it possible to shave quite a few milliseconds from the page loading time but most important of all; to render and display included files but NOT show the source!

This technique will no doubt improve SEO because it will only show your "Golden Content" and reduce the "clutter" such as adverts, banners, superfluous javascript, footers, etc.

Normal loading umpteen images - using PHP include '_snippet.php';
Normal page loading of 1.90 meg images
Notice how long the page takes to load
and epecially the page source code which shows the loaded images

Same '_snippet.php' file using Angular ngInclude
Normal page loading of 1.90 meg images
Notice how long the page takes to load
and epecially the page source code which DOES NOT show the loaded images

Source files:
index.php | _menu_options.php | _snippet.php | style_sheet.css

1. (PHP files extensions need to be changed from TXT)
2. NB: Image files are NOT included.
3. Please set "_snippet.php -> $RELATIVE_FOLDER to your own images folder.
Please feel free to test using any relevant tools.
