Lightbox now does slide shows in tumblr theme

Having previously added the lightbox 2 effect to my tumblr them to display individual photo post images. I wondered about adding the slide show functionality so that all the photo post images on a tumblr page could be displayed. reading through the instructions for lightbox2  it turned out that it is really simple to achieve by adding a group name to the images. The way the tumblr system loops round means that by adding the group name to the theme html once, all photos on the generated page will have the same group name. The group name is added along with the lightbox trigger like this rel=”lightbox[group_name]”

<a href=”{PhotoURL-HighRes}” rel=”lightbox”><img src=”{PhotoURL-500}” alt=”{PhotoAlt}”/>{LinkCloseTag}

<a href=”{PhotoURL-HighRes}” rel=”lightbox[photo_post]”><img src=”{PhotoURL-500}” alt=”{PhotoAlt}”/>{LinkCloseTag}
