index_table_spacing
The thumbnails on the index pages are contained within an
HTML TABLE
, which can have various amounts
of spacing between the thumbnails. You can choose to have
an index page with generous amounts of space between the
thumbnails (“loose”),
miserly amounts of space between the thumbnails
(“tight”), or the minimum amount
possible (“none”).
index_table_spacing
is an unusual variable;
instead of a numeric value or arbitrary string it takes one of
three valid settings: loose,
tight, or none.
