hi i'm working on a portfolio site and i've got a main menu which displays a set of featured image thumbnails that i'd like to link directly to the lightbox. is there a way to wrap the_post_thumbnail() with a link tag? i've tried this(amongst other things):
<a rel="lightbox[post id]>the_post_thumbnail(size)</a>
i probably need to use something as an href but i do not want to go to a new page. i'm probably just overlooking something but i'm also fairly new at coding. can you help?
