Same problem, I've written a my own function to resize the images and it works.

The sizes provided are the limits to decide on which side to calculate the resize.

In example the source image is 200x80, the function should see that the side which exceeds the dimensions is the height and then it should calculate the new sizes according to the height maintaing the aspect ratio, it doesn't have to create a 300x70 image (in the code I made a mistake, the $config['height'] is 70, not 80)

I don't yet have the page online.

HTML validator says: This document was successfully checked as HTML5!
CSS Validator says: Congratulation! No error found.

A real example for the HTML of the menu is

<div id='top-menu-nav'>
	<ul>
		<li><a href="http://www.newsite.com/">Home</a></li>
		<li><a href='#'>Modifica dati</a>
			<ul>
				<li><a href="http://www.newsite.com/users/modifica/user_data.html">Modifica dati personali</a><div class='submenu-divider'></div></li>
				<li><a href="http://www.newsite.com/users/modifica/password.html">Modifica password</a><div class='submenu-divider'></div></li>
				<li><a href="http://www.newsite.com/users/modifica/email.html">Modifica email</a><div class='submenu-divider'></div></li>
			</ul>
		</li>
		<li><a href="http://www.newsite.com/users/ordini.html">I miei ordini</a></li>
		<li><a href="http://www.newsite.com/users/preferiti.html">Shop preferiti</a></li>
	</ul>
</div>

Where the submenu-divider class
is

.submenu-divider {
	width: 15px;
	height: 30px;
	float: right;
	background-image: url('/static/images/submenu_divider.png');
	background-repeat:no-repeat;
	background-position:right top;
}

Solved using SELECT ... FOR UPDATE

Thanks, I'd solved in this way

echo (int) ($decimal_number * pow(10, 2)) / pow(10, 2);
