* The location of the image file. This cannot be an URL.
* Since 7.2.0 this can either be a path to the file (stream wrappers are also supported as usual)

* </p>
* @param string $sections [optional] <p>
* Is a comma separated list of sections that need to be present in file
* to produce a result array. If none of the requested
* sections could be found the return value is <b>FALSE</b>.

* <td>
* html, Width, Height, IsColor, and more if available. Height and
* Width are computed the same way <b>getimagesize</b>
* does so their values must not be part of any header returned.
* Also, html is a height/width text string to be used inside normal
* HTML.

* image size and so forth.

* The EXIF section is a sub section of IFD0. It contains
* more detailed information about an image. Most of these entries
* are digital camera related.

* always become arrays as they may contain values whose names conflict
* with other sections.
* </p>
* @param bool $thumbnail [optional] <p>
* When set to <b>TRUE</b> the thumbnail itself is read. Otherwise, only the
* tagged data is read.

* the header names and the array values are the values associated with
* those headers. If no data can be returned,
* <b>exif_read_data</b> will return <b>FALSE</b>.
