img()

img([$src = ''[, $index_page = FALSE[, $attributes = '']]])

Parameters:	$src (string) – Image source data $index_page (bool) – Whether to treat $src as a routed URI string $attributes (array) – HTML attributes
Returns:	HTML image tag
Return type:	string

Lets you create HTML <img /> tags. The first parameter contains the image source. Example:

echo img('images/picture.jpg'); // gives <img src="http://site.com/images/picture.jpg" />

There is an optional second parameter that is a TRUE/FALSE value that specifics if the src should have the page specified by $config['index_page'] added to the address it creates. Presumably, this would be if you were using a media controller:

echo img('images/picture.jpg', TRUE); // gives <img src="http://site.com/index.php/images/picture.jpg" alt="" />

Additionally, an associative array can be passed to the img() function for complete control over all attributes and values. If an alt attribute is not provided, CodeIgniter will generate an empty string.

Example:

$image_properties = array(
        'src'   => 'images/picture.jpg',
        'alt'   => 'Me, demonstrating how to eat 4 slices of pizza at one time',
        'class' => 'post_images',
        'width' => '200',
        'height'=> '200',
        'title' => 'That was quite a night',
        'rel'   => 'lightbox'
);

img($image_properties);
// <img src="http://site.com/index.php/images/picture.jpg" alt="Me, demonstrating how to eat 4 slices of pizza at one time" class="post_images" width="200" height="200" title="That was quite a night" rel="lightbox" />
