Yes prettyPhoto is deactivated by default. You can easily activate it by “uncommenting” the code, and then “commenting out” the code right above it.
Here is the code you’ll need to “uncomment” –
/**
* Opens Featured Images with prettyPhoto Slideshow
*
* @author Wes Straham
* @since 1.0.0
*/
/*add_action( 'genesis_before_post_content', 'epik_prettyPhoto_image' );
function epik_prettyPhoto_image() {
$img = genesis_get_image( array( 'format' => 'html', 'size' => 'portfolio-thumbnail', 'attr' => array( 'class' => 'alignnone post-image' ) ) );
printf( '<a href="%s" rel="prettyPhoto[gallery1]" title="%s">%s</a>', genesis_get_image( array( 'format' => 'url', 'size' => 'Portfolio Full', 'attr' => array( 'class' => 'alignnone post-image' ) ) ), the_title_attribute('echo=0'), $img );
}
*/
The code right above that looks like this –
/**
* Adds Featured Image and links it to the Post
*
* @author Wes Straham
* @since 1.0.0
*/
add_action( 'genesis_entry_header', 'optimal_portfolio_do_post_image' );
function optimal_portfolio_do_post_image() {
$img = genesis_get_image( array( 'format' => 'html', 'size' => 'portfolio-thumbnail', 'attr' => array( 'class' => 'alignnone post-image' ) ) ); printf( '<a href="%s" title="%s">%s</a>', get_permalink(), the_title_attribute('echo=0'), $img );
}
