Returns the maximal amount of columns in the directory table.

get_max_columns_image()

Returns the maximal amount of columns in the image table.

get_size( [ INDEX_ARRAY ] )

Returns an ARRAY containing the list of size description objects for the file. INDEX_ARRAY is an optional list of indexes which when specified causes only the indexed elements in the ordered list to be returned. If not specified, all elements are returned.
