Hey, I’m having the same issue and this seems to be the most informative solution I’ve come across. I’ve been at this for weeks! Basically, what I’m trying to do is get the featured images on my homepage to link to another url besides the post itself. I hope to set a youtube link as that url so the featured image opens in lightbox as a video within the page. My first stab at making that happen is actually being able to set the featured image to link somehwere other than the full post. creating a custom field seems like the way to go. Lovduv, where would I place those codes? index.php?
