Parameters

$field: The field the action is being performed on.

$item: An array, keyed by column, of the data stored for this item in this field.

$formatter: The formatter to use for the field.

$node: The node object.

$options: Array of options available. Not used in this theme function but required by the invoked emfield function.

File

./lightbox2.module, line 2046

Enables the use of lightbox2 which places images above your current page, not within. This frees you from the constraints of the layout, particularly column widths.
