If $_POST["image_loc"] is remote url, you can use function below that returns file size. So can check if it returns 0 or not. If $_POST["image_loc"] isn't remote url and it's image path in your server, you can simply use filesize($image_path) function to get image size.

function get_image_size($image_url){
 $ch = curl_init($image_url);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
 curl_setopt($ch, CURLOPT_HEADER, TRUE);
 curl_setopt($ch, CURLOPT_NOBODY, TRUE);
 $data = curl_exec($ch);
 $size = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);
 curl_close($ch);
 return $size;
}
