+Themes
+------
+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
+
+If any of the functions are not defined in a theme then the default theme
+function will be used instead. The default theme is clean and simplistic, this
+is deliberate!
