exif_thumbnail — Retrieve the embedded thumbnail of an image
$file,&$width = null,&$height = null,&$image_type = nullexif_thumbnail() reads the embedded thumbnail of an image.
If you want to deliver thumbnails through this function, you should send the mimetype information using the header() function.
It is possible that exif_thumbnail() cannot create an
image but can determine its size. In this case, the return value is
false but width and height
are set.
fileThe location of the image file. This can either be a path to the file or a stream resource.
widthThe return width of the returned thumbnail.
heightThe returned height of the returned thumbnail.
image_typeThe returned image type of the returned thumbnail. This is either TIFF or JPEG.
Returns the embedded thumbnail, or false if the image contains no
thumbnail.

and stream resources.
