Linking featured image to Large image

[Morten]

I'm using the Generate theme, and I trying to make the featured image link to a large version of the image instead of the post itself, but only on single posts.
I can make part of this happen (probably not the right way though) by changing "Get_permalink()" to "$image_lightbox" and adding the following to function.php
"if ( $image_lightbox = genesis_get_image( array( 'format' => 'url', 'size' => ( 'large' ) ) ) ) "
The problem is that this also changes the link on the blog/archive pages. I tried messing around with "if ( is_single" )" but can't get it to work
Can anyone help me or point me in the right direction
Thanks
Morten

What is the full function you're using? How did you add in the conditional tag?

I just changed the existing code a little, added the bolded line and changed the get_permalink()

 

/** Add custom post image above post title */
add_action( 'genesis_before_post_content', 'generate_post_image', 5 );
function generate_post_image() {

if ( is_page() || ! genesis_get_option( 'content_archive_thumbnail' ) )
return;
if ( $image_lightbox = genesis_get_image( array( 'format' => 'url', 'size' => ( 'large' ) ) ) )

if ( $image = genesis_get_image( array( 'format' => 'url', 'size' => genesis_get_option( 'image_size' ) ) ) ) {
printf( '<a href="%s" rel="bookmark"><img class="post-image" src="%s" alt="%s" /></a>', $image_lightbox, $image, the_title_attribute( 'echo=0' ) );
}

}
