This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

• detail => bool

  Whether to show detailed records.

  The default is to show detailed records when there are more than 1 filenames specified; when there is only 1 filename, will only show dimension in WxH format (e.g. 640x480). If this option is specified, will show detailed records even if there is only one filename specified.

• filenames* => array[filename]

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)
