Check whether image exists on remote URL
function checkRemoteFile($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); $result = curl_exec($ch); curl_close($ch); if($result !== FALSE) { return true; } else { return false; }}
--> that is the fastest way if your host supports curl
