Moved this site on to a VPS from IntoVPS

Few days ago, I moved this website on to a VPS from IntoVPS. So far IntoVPS has been quite good. It took only few minutes to get access to my VPS after signing up on IntoVPS site.

Embedding height and width attributes reduces the amount of repainting that the browser needs to do while rendering a webpage.

Here is sample code, which embeds a User’s Profile Picture.

<?php echo theme('image', $u->picture, $u->name, $u->name, array('class' => 'content_img')); ?>
