    Use getimagesize() to ensure that the URL points to a valid image.

    if (getimagesize($imageURL) !== false) {
        // display image
    }

    function is_webUrl($url) {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        // don't download content
        curl_setopt($ch, CURLOPT_NOBODY, 1);
        curl_setopt($ch, CURLOPT_FAILONERROR, 1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        if (curl_exec($ch) !== FALSE) {
            return true;
        } else {
            return false;
        }
    }

    function exists($uri)
    {
        $ch = curl_init($uri);
        curl_setopt($ch, CURLOPT_NOBODY, true);
        curl_exec($ch);
        $code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        curl_close($ch);
    
        return $code == 200;
    }
