Question

I’ve wrote a short script to upload images from a URL so as not to hotlink to them. If the image extension is not a .jpeg then the image that is uploaded is broken. I can’t figure out how to preserve the file extension or filename so I’ve had to add a timestamp to them and a static extension.

<?php

    ini_set('user_agent', 'TEST/1.0 +http://127.0.0.1');

    require_once('simple_html_dom.php');

    // Create DOM from URL
    $html = file_get_html('http://www.discogs.com/viewimages?release='.$_POST["album_id"]);

    // Grab the coverart
    $img = $html->find('.image_frame', 0);

    $url = $img->src;

    $file = file_get_contents($url);

    $image = 'discogs_'.time().'_image.jpeg';

    file_put_contents('/path/to/file/'.$image,$file);

    echo $image;

?>

You can try using getimagesize with image_type_to_extension

require_once('simple_html_dom.php');
$url = "http://www.discogs.com/viewimages?artist=Test+%282%29";
$html = file_get_html($url);
$img = $html->find('.image_frame', 0);
$info = getimagesize($img->src);
$extention = image_type_to_extension($info[2]);
$image = 'discogs_'.time().'_image' . $extention;
echo $image ;

Output
