Antonio,
everything looks great, but I am thinking about security....
I am testing your samples in my own computer in localhost, and I have all your images, code Html, JavaScript and CSS; which I got by just using Google's Chrome Developer tools...
That means that all your code will be visible and will give you a Security risk, because your data will be exposed and your entire aplication can be copied!!!
That is the reason why I think it will be wise to use more PHP and less JavaScript or make the calls to JavaScrip from a .PHP file, because (I am not certain) but I think it will be hidden...
EDITED:
Just tested and the JavaScript is shown even in a PHP file, but everything contained between <?php ?> would not be shown... Plus PHP will give you easy access to MySQL...
By using lots of PHP, at least the applications will be useless when copied...
