DigiKam to PHP Photo Album - Album Pages
The album pages can be a group of images within an album, a group of albums, or a group of images based on a tag (possibly within an album). The display of both are handed by a single page, index.php
I have some formatting in there to make these pages fit-in with the rest of my site (much of the detail is pulled in with "server-side-includes"). The page itself has a little bit of logic to get the album/group/tag ids from the query parameters, then it calls into the album library to format the elements on the page.
