exif_thumbnail — Retrieve the embedded thumbnail of an image

### Descrierea

exif_thumbnail ( mixed `$stream` [, int `&$width` [, int `&$height` [, int `&$imagetype` ]]] ) : string

exif_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.

### Parametri

`stream`

  The location of the image file. This can either be a path to the file or a stream resource.

`width`

  The return width of the returned thumbnail.

`height`

  The returned height of the returned thumbnail.

`imagetype`

  The returned image type of the returned thumbnail. This is either TIFF or JPEG.

### Valorile întoarse

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

### Exemple

Example #1 exif_thumbnail() example

`<?php
$image = exif_thumbnail('/path/to/image.jpg', $width, $height, $type);
if ($image!==false) {
header('Content-type: ' .image_type_to_mime_type($type));
echo $image;
exit;
} else {
// no thumbnail available, handle the error here
echo 'No thumbnail available';
}
?>`
