exif_thumbnail

(PHP 4 >= 4.2.0, PHP 5, PHP 7)

exif_thumbnailRetrieve the embedded thumbnail of an image

Description

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

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.

Parameters

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.

Return Values

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

Examples

Example #1 exif_thumbnail() example

<?php
$image 
exif_thumbnail('/path/to/image.jpg'$width$height$type);

$image!==false) {
    
header('Content-type: ' .image_type_to_mime_type($type));
    echo 
$image;
    exit;
} else {
    
// no thumbnail available, handle the error here
