Am I missing the point of object oriented programming?

Question

Recently, I took on the task of trying to learn OO programming. It has been about three months since I started, but I think it might not make sense, because I prefer static methods (which seem "easier" to me).

Example

This is what a typical DB query looks like in my code.

$bindings = array(':name'=>$articleName);

Db::query('SELECT id, name, title, image, content FROM ' . CONFIG_MYSQL_TABLE_PREFIX . 'articles WHERE name = :name LIMIT 1', $bindings);

And this is how I resize / crop / cache images

$image = Img::thumbnail($imagePath, 200);

$imgHtml = '<img alt="' . $this->getTitle() . '" src="' . '' . $image['src'] . '" width="' . $image['width'] . '" height="' . $image['height'] . '" />';

Both static methods use a singleton pattern. the first creates one PDO, and the second creates one ImageResize class, which I found in Google code.

If these are two objects, if I really wanted to call it object-oriented programming? i.e.

$db = new Db();

$image = new Image($src, $width, $height);
