-Theme support is very rudimentary, basically you create functions for each of the parts of the template, and put them in a file named the same as the theme. The functions that you need to declare are as follows:
-       bpgallery_ThemeName_head()
-               what's it for?:
-                       This sets up the header for the page, generally
-                       everything until the first picture. So, the title bar
-                       and any menus you would like to use
-               available variables:
-                       $TITLE       - the title for the index page
-       bpgallery_ThemeName_tail()
-               what's it for?:
-                       Closes the page, is the last thing to be printed.
-               available variables:
-                       None
-       bpgallery_ThemeName_description()
-               what's it for?:
-                       if there's a description set up (i.e. a description.txt
-                       file) then this is what it'll be wrapped in. It comes
-                       just after the _head.
-               available variables:
-                       $DESCRIPTION - the content of description.txt
-       bpgallery_ThemeName_stylesheet()
-               what's if for?:
-                       It generates the stylesheet for the page.
-               available variables:
-                       $WIDTH       - the width of the images
-                       $MAXHEIGHT   - the maximum height of the image
-       bpgallery_ThemeName_thumbsline()
-               what's it for?:
-                       Whatever is in here is generated per thumbnail.
-               available variables:
-                       $filename    - the name of the file
-                       $caption     - the caption as got from captions.txt
