I'm working with Post-Tiles and using the shortcode from my nextgen gallery. I want to click the tile and have it open a lightbox. Downside is I don't think nextgen or any lightbox plugin is compatible that way. I was trying to get the pop up image through the featured image, but I am now thinking I need to get the image through the [singlepic] short code. Any recommendations? Or am I on the wrong path?
