exif_thumbnail - Retrieve the embedded thumbnail of a TIFF or JPEG image

SYNOPSIS

       string exif_thumbnail (string  $filename, [int  &$width], [int  &$height], [int	&$imagetype])

DESCRIPTION

       exif_thumbnail(3) reads the embedded thumbnail of a TIFF or JPEG image.

	If you want to deliver thumbnails through this function, you should send the mimetype information using the header(3) function.

	It  is	possible  that	exif_thumbnail(3)  cannot  create an image but can determine its size. In this case, the return value is FALSE but
       $width and $height are set.

PARAMETERS

	      o $filename
		- The name of the image file being read. This image contains an embedded thumbnail.

	      o $width
		- The return width of the returned thumbnail.

	      o $height
		- The returned height of the returned thumbnail.

	      o $imagetype
		- The returned image type of the returned thumbnail. This is either TIFF or JPEG.

RETURN VALUES

	Returns the embedded thumbnail, or FALSE if the image contains no thumbnail.
